    in part filed by Circuit Judge KAVANAUGH.
    Opinion concurring in part and concurring in the judgment
    filed by Senior Circuit Judge SENTELLE.
    GRIFFITH, Circuit Judge: Robert Gordon owns a business
    that sold tobacco products across state lines. In the district
    court, Gordon sought a preliminary injunction against the
    enforcement of provisions of the Prevent All Cigarette
    Trafficking Act (PACT Act) that require him to pay state and
    local taxes and ban him from sending his products through the
    U.S. mail. Gordon argues that the tax provisions violate the
    Due Process Clause and the Tenth Amendment and that the
    5
    mail ban runs afoul of the Due Process and Equal Protection
    Clauses.
    The district court enjoined the enforcement of the tax
    provisions on due process grounds, but otherwise dismissed
    Gordon’s claims. The government appeals the preliminary
    injunction, and Gordon cross-appeals the district court’s
    dismissal of, and refusal to grant a preliminary injunction for,
    his remaining claims. For the reasons set forth below, we
    affirm the district court’s decision in its entirety.
    I
    A
    In most states, the liability for sales and use taxes falls
    primarily on the buyer. U.S. Government Accountability
    Office, GAO-03-714T, Internet Cigarette Sales: Limited
    Compliance and Enforcement of the Jenkins Act Result in Loss
    of State Tax Revenue 3 (2003) (hereinafter GAO Report);
    WALTER HELLERSTEIN, STATE TAXATION ¶ 12.01 (3d ed.
    2012). States require retailers to collect applicable taxes from
    resident buyers and remit the receipts to the state. STEVEN
    MAGUIRE, CONGRESSIONAL RESEARCH SERV., STATE
    TAXATION OF INTERNET TRANSACTIONS 1 (2013). A state may
    not, however, impose such an obligation on a retailer with
    whom the state lacks minimum contacts. See Quill Corp. v.
    North Dakota, 
    504 U.S. 298
     (1992). 1 This means that most
    1
    The minimum contacts requirement derives from the Due
    Process Clause. The Due Process Clause is not the only provision of
    the Constitution that limits states’ authority to tax: the so-called
    Dormant Commerce Clause prohibits states from requiring retailers
    with whom the state lacks a “substantial nexus” to collect taxes,
    absent congressional authorization. Quill, 
    504 U.S. at 311
    . The
    6
    out-of-state retailers operate beyond the state’s regulatory
    reach. When they cannot rely on retailers to collect taxes, states
    find it both expensive and difficult to track the smaller
    out-of-state purchases of their residents and to collect the
    applicable taxes directly from them. This creates an
    opportunity for tax evasion that is especially costly when it
    comes to goods like tobacco products that are taxed at high
    rates. GAO Report, supra, at 7. In an effort to eliminate this
    opportunity for tobacco buyers, Congress passed the Jenkins
    Act, which obligates retailers to report each interstate sale of
    tobacco products to the tax authority of the consumer’s state.
    Pub. L. No. 81-363, 
    63 Stat. 884
     (1949).
    More than a half century has elapsed since the passage of
    the Jenkins Act, and as the Internet has made it easier for
    consumers to order tobacco products from out-of-state sellers,
    it has become more difficult for states and localities to collect
    taxes on these transactions. H.R. Rep. No. 111-117, at 18-19
    (2009); see also GAO Report, supra, at 8, 12-13. Remote
    purchasing also makes it easier for parties to evade age
    restrictions and otherwise traffic in cigarettes illegally. 
    15 U.S.C. § 375
     note; see also H.R. Rep. No. 111-117, at 18.
    Dormant Commerce Clause “nexus” test may be more demanding
    than the Due Process Clause “minimum contacts” test, see id. at 313,
    317-18, but it is not at issue in this case because Gordon challenges a
    federal statute.
    My concurring colleague criticizes this footnote as
    “gratuitous.” Post, at 1 (Sentelle, J., concurring). I disclaim any
    attempt to opine on the effect of the Dormant Commerce Clause,
    which, as my colleague correctly points out, is not at issue in this
    case. I include this incontrovertible description of the Supreme
    Court’s Dormant Commerce Clause doctrine only to clarify that the
    Due Process Clause is not the only provision that restricts a state’s
    power to tax out-of-state retailers.
    7
    Finding the Jenkins Act inadequate, H.R. Rep. No. 111-117, at
    18, Congress has sent the PACT Act into the breach.
    The PACT Act is “aimed primarily at combating three
    evils: tobacco sales to minors, [illicit] cigarette trafficking, and
    circumvention of state taxation requirements.” Gordon v.
    Holder (Gordon I), 
    632 F.3d 722
    , 723 (D.C. Cir. 2011). It does
    so by restricting “delivery sales” of cigarettes and smokeless
    tobacco products. A delivery sale is any sale in which either the
    purchase or the delivery does not occur face-to-face. 
    15 U.S.C. § 375
    (5). Two sections of the Act are at issue here. Section 2a
    prohibits delivery sales unless all applicable state and local
    taxes are paid “in advance of the sale, delivery, or tender.” 15
    U.S.C. § 376a(a)(3)-(4), (d). Delivery sellers must comply
    with “all State, local, tribal, and other laws generally applicable
    to sales of cigarettes or smokeless tobacco as if the delivery
    sales occurred entirely within the specific State,” meaning that
    they must collect any taxes that state or local laws require
    in-state retailers to collect. 15 U.S.C. § 376a(a)(3). They are
    subject to federal criminal and civil penalties if the applicable
    taxes have not been paid in advance. 15 U.S.C. § 376a(d)(1)
    (prohibition); 
    15 U.S.C. § 377
     (penalties). Section 3 prohibits
    sending tobacco products in the U.S. mail. 18 U.S.C. § 1716E.
    As a result, tobacco delivery sellers must resort to private
    carriers.
    B
    According to his complaint, Robert Gordon ran a business
    selling tobacco products in the Alleghany Territory of the
    Seneca Nation of Indians, located in western New York. After
    starting his business in 2002, Gordon accepted orders in
    person, over the phone, and occasionally online. At the height
    of his business, Gordon took in two million dollars in revenue
    every month. Ninety-five percent of that revenue came from
    8
    sales to customers outside of New York. Gordon claims,
    however, that he has never made a sale into some state and
    local taxing jurisdictions within the United States. See Marcia
    Gordon Second Decl. ¶ 13.
    Gordon asserts that his business has suffered under the
    PACT Act. Until recently, Gordon has enjoyed the protection
    of a Western District of New York preliminary injunction
    against the enforcement of the tax provisions, 2 but the mail
    ban has taken its toll. The major private carriers – Federal
    Express, United Parcel Service, and DHL – also refuse to
    deliver tobacco products, leaving Gordon with only more
    expensive couriers. On May 30, 2013, while this appeal was
    pending, Gordon notified the court that he has found it
    necessary to close his business.
    C
    Gordon’s case has been before us already. Gordon v.
    Holder (Gordon I), 
    632 F.3d 722
     (D.C. Cir. 2011). On June 28,
    2010, the day before the PACT Act took effect, Gordon filed a
    complaint alleging that the tax provisions and the mail ban are
    unconstitutional and sought a preliminary injunction against
    2
    A group of plaintiffs brought a similar challenge to the PACT
    Act in the Western District of New York, and that district court
    granted a preliminary injunction against enforcement of the tax
    provisions on due process grounds. See Red Earth LLC v. United
    States, 
    728 F. Supp. 2d 238
     (W.D.N.Y. 2010). The Second Circuit
    upheld the preliminary injunction. Red Earth LLC v. United States,
    
    657 F.3d 138
     (2d Cir. 2011) (per curiam). On June 7, 2013, the
    parties voluntarily stipulated to dismissal with prejudice, and the
    court vacated the injunction. See Stipulation and Order of Dismissal,
    Red Earth LLC v. United States, No. 10-CV-530 (W.D.N.Y. June 7,
    2013).
    9
    their enforcement. Id. at 723. The district court denied
    Gordon’s motion the next day on the sole ground that it was too
    late to stop the Act from taking effect. Id. at 724. Gordon
    appealed.
    We remanded Gordon’s motion to the district court to
    consider the factors a plaintiff must demonstrate to obtain a
    preliminary injunction. Gordon I, 
    632 F.3d at 726
    . On remand,
    the district court enjoined the tax provisions on due process
    grounds, but dismissed for failure to state a claim Gordon’s
    Tenth Amendment challenge to the tax provisions and his due
    process and equal protection challenge to the mail ban. See
    Gordon v. Holder, 
    826 F. Supp. 2d 279
     (D.D.C. 2011). Both
    parties appealed.
    We have jurisdiction to review the resolution of Gordon’s
    motion for a preliminary injunction under 
    28 U.S.C. § 1292
    (a)(1), and the dismissal of his claims under 
    28 U.S.C. § 1291
    . The closure of Gordon’s business has not mooted his
    appeal. His wife submitted a sworn declaration that she and
    Gordon intend to reopen their business if they prevail, and that
    they remain capable of doing so. Marcia Gordon Third Decl.
    ¶¶ 5-7. Gordon’s “uncontroverted intention to operate in the
    future in ways that would violate” the PACT Act “keeps the
    controversy alive.” See Unity08 v. FEC, 
    596 F.3d 861
    , 864
    (D.C. Cir. 2010). 3
    3
    Because we are required to ascertain our jurisdiction before
    proceeding to the merits of an appeal, see Steel Co. v. Citizens for a
    Better Env’t, 
    523 U.S. 83
     (1998), our conclusion that the closure of
    Gordon’s business does not moot this case is final. Naturally, facts
    may develop that moot the case in the future, at which point the
    district court would be required to dismiss Gordon’s complaint. But
    the district court is not, as our concurring colleague seems to suggest,
    10
    II
    As we explained in Gordon I, “‘[a] plaintiff seeking a
    preliminary injunction must establish that he is likely to
    succeed on the merits, that he is likely to suffer irreparable
    harm in the absence of preliminary relief, that the balance of
    the equities tips in his favor, and that an injunction is in the
    public interest.’” 
    632 F.3d at 724
     (quoting Winter v. Natural
    Res. Def. Council, 
    555 U.S. 7
    , 20 (2008)). We review the
    “district court’s weighing of the four preliminary injunction
    factors and its ultimate decision to issue or deny such relief for
    abuse of discretion.” Davis v. Pension Benefit Guar. Corp.,
    
    571 F.3d 1288
    , 1291 (D.C. Cir. 2009). We review the district
    court’s legal conclusions de novo and its findings of fact for
    clear error. In re Navy Chaplaincy, 
    697 F.3d 1171
    , 1178 (D.C.
    Cir. 2012). But, as the Supreme Court admonished in Ashcroft
    v. ACLU, where “the underlying constitutional question is
    close” we must “uphold the injunction and remand for trial on
    the merits.” 
    542 U.S. 656
    , 664-65 (2004); see also Red Earth
    LLC v. United States, 
    657 F.3d 138
    , 145 (2d Cir. 2011) (per
    curiam) (“Because the district court reached a reasonable
    conclusion on a close question of law, there is no need for us to
    decide the merits at this preliminary stage.”). Under Ashcroft,
    if the district court’s analysis of the preliminary injunction
    factors reflects a reasonable conclusion about a close question
    of constitutional law, and contains no other legal error, then we
    must send the case back to the district court with the
    preliminary injunction intact. We must refrain from resolving
    novel and difficult constitutional questions, leaving them to be
    post, at 1 (Sentelle, J., concurring), free to revisit our holding that the
    case is currently an Article III case or controversy.
    11
    settled at a later stage, with the benefit of further factual and
    legal development.
    The government and dissent argue that Ashcroft’s gloss on
    the standard of review applies only to preliminary injunctions
    based on the First Amendment, when the government bears a
    special burden to justify the challenged law with a compelling
    governmental interest. Appellants’ Reply Br. 16 n.9 (citing
    Gonzales v. O Centro Espirita Beneficente Uniao do Vegetal,
    
    546 U.S. 418
    , 429-30 (2006)). We disagree. The Ashcroft
    Court expressly derived its deferential approach “from
    established standards of appellate review” set out in Walters v.
    National Association of Radiation Survivors – a case involving
    a preliminary injunction based, like the one here, on the Due
    Process Clause. Ashcroft, 
    542 U.S. at 664
     (quoting Walters,
    
    473 U.S. 305
    , 336 (1985) (O’Connor, J., concurring)). Our
    sister circuits have also applied Ashcroft’s standard of review
    to preliminary injunctions based on due process challenges.
    See Red Earth, 
    657 F.3d at 145
     (applying Ashcroft to an
    identical due process challenge to the PACT Act);
    Reproductive Health Serv. of Planned Parenthood of St. Louis
    Region v. Nixon, 
    428 F.3d 1139
    , 1145 (8th Cir. 2005)
    (applying Ashcroft to a constitutional challenge to an abortion
    regulation). In fact, we find no case expressly limiting
    Ashcroft’s command to First Amendment challenges. To be
    sure, Ashcroft was a First Amendment case, and certain
    features of the Court’s analysis naturally have no bearing
    outside the First Amendment context. For example, the Court
    affirmed the district court’s conclusion that the plaintiff was
    likely to succeed on the merits because the government had not
    met its special First Amendment burden to justify the
    challenged restrictions on speech with a compelling
    governmental interest. See Gonzales, 
    546 U.S. at 429
    (describing Ashcroft). But the Ashcroft Court’s description of
    our standard of review is not so restricted. It reflects the
    12
    general principle that, even though Congress has provided for
    interlocutory review of preliminary injunctions, premature
    resolution of difficult constitutional questions is undesirable.
    Cf. Pearson v. Callahan, 
    555 U.S. 223
    , 239 (2009) (describing
    the dangers of premature resolution of constitutional
    questions); Mitchell v. Forsyth, 
    472 U.S. 511
    , 549-50 (1985)
    (Brennan, J., dissenting) (“[R]esolution of even the most
    abstract legal disputes is advanced by the presence of a
    concrete set of facts.”). Thus, the Court’s command to uphold
    the injunction when “the underlying constitutional question is
    close” binds us today.
    We conclude that the district court did not abuse its
    discretion by entering a preliminary injunction.
    A
    We begin with the district court’s assessment of Gordon’s
    likelihood of success on the merits, which is left untouched by
    the closure of Gordon’s business. The district court held that
    Gordon is likely to succeed on the merits of his due process
    challenge. Gordon, 826 F. Supp. 2d at 293. Because we find
    the underlying constitutional questions to be close, we affirm
    the district court’s conclusion. See Ashcroft, 
    542 U.S. at 664-65
    . 4
    4
    For this reason, contrary to my concurring colleague’s
    statement, Part II.A “elevat[es]” nothing “to circuit law.” Post, at 1
    (Sentelle, J., concurring). The legal premises of Gordon’s due
    process challenge remain fair game on remand; we merely conclude
    that the questions they raise are too close to call at this stage. See
    Sherley v. Sebelius, 
    689 F.3d 776
    , 781 (D.C. Cir. 2012) (“[T]he
    decision of a trial or appellate court whether to grant or deny a
    preliminary injunction does not constitute law of the case for the
    purpose of further proceedings and does not limit or preclude the
    parties from litigating the merits.” (citation omitted)).
    13
    Gordon argues that the PACT Act “violates nonresident
    tobacco retailers’ due process rights . . . by subjecting them to
    taxes in state and local forums without regard to whether they
    have minimum contacts with the taxing jurisdiction.” 5
    Appellee’s Br. 21. This argument presents two substantial and
    novel constitutional questions. First, does the Due Process
    Clause require minimum contacts between the state or local
    taxing authority and the nonresident seller even when the
    federal government is the source of the seller’s duty to collect
    taxes? And second, if due process requires minimum contacts
    with the state or local taxing jurisdiction, does a single delivery
    sale to a buyer in that jurisdiction create minimum contacts?
    Both are questions of law, but they are matters of first
    impression, and their resolution would benefit from fuller
    factual development below. See Pearson, 
    555 U.S. at 239
    . We
    do not settle them here because we need not do so to affirm the
    preliminary injunction.
    1
    Although it is well-settled that the Due Process Clause
    requires minimum contacts between the taxing sovereign and
    the taxed entity, see Miller Bros. Co. v. Maryland, 
    347 U.S. 340
    , 342, 344-45 (1954), this appeal presents a unique twist on
    that principle: with which sovereign must the taxed entity
    possess minimum contacts when there is one sovereign that
    defines and benefits from the tax obligation (in this case, the
    state or local government), and another that imposes and
    5
    As discussed above, Gordon is formally “collecting” taxes
    owed by the buyer and remitting them to the state, rather than paying
    them. Under the Due Process Clause, we treat an obligation to collect
    taxes the same as an obligation to pay taxes. See Quill, 
    504 U.S. at 319
     (Scalia, J., concurring) (collecting cases).
    14
    enforces the obligation (in this case, the federal government)?
    Gordon and the government think that the question can be
    resolved by reference to precedent. We do not. This question is
    novel and close, and we cannot say that the district court’s
    conclusion that Gordon is likely to succeed on the merits is an
    abuse of discretion. We are therefore bound to affirm its
    determination. See Ashcroft, 
    542 U.S. at 664-65
    .
    For its part, the government argues that the Act is
    constitutional because Gordon has minimum contacts with the
    federal government, the sovereign that imposed and will
    enforce his tax obligations. The government correctly points
    out that this is not the first time a seller has challenged
    Congress’s power to oblige participants in interstate commerce
    to comply with state-defined duties. The Supreme Court has
    twice upheld federal laws against similar challenges – one to
    the Ashurst-Sumners Act and one to the Webb-Kenyon Act.
    See Ky. Whip & Collar Co. v. Ill. Cent. Ry. Co., 
    299 U.S. 334
    (1937); James Clark Distilling Co. v. W. Maryland Ry. Co.,
    
    242 U.S. 311
     (1917). The Ashurst-Sumners Act made “it
    unlawful knowingly to transport in interstate or foreign
    commerce goods made by convict labor into any State where
    the goods are intended to be received, possessed, sold, or used
    in violation of its laws.” Kentucky Whip & Collar Co., 
    299 U.S. at 343
    . The Webb-Kenyon Act prohibited “the
    transportation in interstate commerce of all liquor
    ‘intended . . . to be received, possessed, sold, or in any manner
    used . . . in violation of any law of” the destination state. James
    Clark Distilling Co., 
    242 U.S. at 321
    . In both cases, the
    Supreme Court deemed it irrelevant that the states defined the
    companies’ legal duties because the “will” behind the two laws
    was Congress’s, not the states’. Ky. Whip & Collar Co., 
    299 U.S. at 347-52
    ; James Clark Distilling Co., 
    242 U.S. at 326
    .
    The “will” behind the PACT Act is also Congress’s, so the
    government argues that these precedents require us to
    15
    disregard the role the states play in defining Gordon’s legal
    duties. Appellants’ Br. 25, 27; see also Musser’s Inc. v. United
    States, No. 10-4355, 
    2011 WL 4467784
    , *5 (E.D. Pa. Sept. 26,
    2011) (“[T]he Act’s tax-payment requirement is not being
    imposed by a state, acting unilaterally, but by Congress, and
    the legislative due process analysis must reflect the federal
    character of the legislation.”). Because Congress’s “will”
    converts the state taxes into federal duties, the argument goes,
    the Due Process Clause demands minimum contacts only
    between Gordon and the federal government.
    The government’s argument overlooks an important
    distinction: The challenges to the federal statutes at issue in
    James Clark Distilling Company and Kentucky Whip & Collar
    Company were brought under the Commerce Clause; unlike
    Gordon’s challenge, they raised no issue of minimum contacts
    under the Due Process Clause. 6 See James Clark Distilling
    6
    The parties in those cases raised due process challenges, but
    not of the sort we consider here. See James Clark Distilling Co., 
    242 U.S. at 320

    clause, forbid the manufacture and sale of liquor and regulate its
    traffic, is not open to controversy . . . .”);

    necessary to point out that the considerations which we have stated

    to state power is decisive.”); Ky. Whip & Collar Co.,

    The government and the dissent, post, at 2-3 (Kavanaugh, J.,

    “As the Supreme Court has explained, the inquiries are
    analytically distinct and should not be treated as if they were
    synonymous.” Gordon I, 
    632 F.3d at 725
     (citation omitted).
    Congress’s “will” was enough to cure any Commerce Clause
    defect in the Ashurst-Sumners and Webb-Kenyon Acts
    because Congress may authorize states to regulate interstate
    commerce. 
    Id.
     But a medicine that cures one ailment may be
    feckless against the next. No doctor would prescribe penicillin
    for a broken arm; nor will we uncritically hand out the
    Supreme Court’s Commerce Clause prescription when a
    litigant comes to us complaining of a due process injury.
    Congress’s “will” might cure the due process injury that would
    otherwise arise if the states tried unilaterally to impose taxes on
    Gordon. But to reach that conclusion, we must conduct a closer
    exception is the Jenkins Act, which a three judge district court once
    upheld against a due process challenge. See Consumer Mail Order
    Ass’n of Am. v. McGrath, 
    94 F. Supp. 705
     (D.D.C. 1950). But that
    Act is distinguishable because the federal government imposed,
    defined, and enforced the duty, rather than incorporating a duty
    created by state law. See 
    15 U.S.C. § 376
     (setting out detailed
    requirements for the report the seller must submit to the state).
    All of these federal laws are distinguishable from the PACT Act
    for an additional reason: the state laws they incorporate do not
    impose a duty to collect taxes; they regulate commercial activity
    instead. The Court has long held that mere contact through the U.S.
    mail provides the “minimum contact” required for a state to assert
    regulatory, as distinguished from taxation, jurisdiction. See
    Travelers Health Ass’n v. Virginia ex rel. State Corp. Comm’n, 
    339 U.S. 643
    , 646-50 (1950). For that reason, the laws cited by the
    government and the dissent arguably satisfy the Due Process Clause
    even if Gordon is correct that the Clause requires minimum contacts
    between the seller and the state or locality.

    substantial justice.” 
    Id.
     (internal quotation marks omitted).
    Sensitive to the distinctions between the Due Process and
    Commerce Clauses, Gordon argues that the answer to this
    question is found in the principles set out in Quill Corp. v.
    North Dakota, 
    504 U.S. 298
     (1992). In Quill, an out-of-state
    mail-order catalogue business challenged a state law that
    compelled “every person who engages in regular or systematic
    solicitation of a consumer market in” North Dakota to collect
    use taxes from its customers and remit them to the state. 
    Id. at 302-03
     (internal quotation marks omitted). Even though Quill
    was a Delaware corporation with no physical presence in North
    Dakota, the state statute required the company to collect North
    Dakota use taxes because it engaged in “regular or systematic
    solicitation” in the state, as defined by the statute. 
    Id.
     (internal
    quotation marks omitted). Quill challenged the law under the
    Due Process and Commerce Clauses. 
    Id. at 303-04
    . Before
    addressing these separate challenges, the Court discussed the
    differences between the clauses as they relate to the state’s
    power to regulate an entity located in another state. 
    Id. at 305-06
    . In dicta, the Court explained: “While Congress . . .
    may authorize state actions that burden interstate commerce, it
    does not similarly have the power to authorize violations of the
    Due Process Clause.” 
    Id. at 305
     (internal citations omitted).
    Then, the Court set out the fundamental rule that the Due
    Process Clause requires minimum contacts between the taxing
    sovereign and the taxed entity. 
    Id. at 306
    . Taken together,
    Gordon argues, the legal principles set forth in Quill prohibit
    Congress from imposing state or local taxes on out-of-state
    sellers who lack minimum contacts with the state or locality.
    Even the government concedes that, after Quill, Congress
    may not authorize a state to impose the duty to collect state use
    taxes on delivery sellers lacking minimum contacts with the
    18
    state. But that is not what the PACT Act does. Section 2a does
    not address itself to states at all. Rather than authorizing the
    states to impose on Gordon a state duty to collect state taxes,
    the PACT Act imposes on Gordon a federal duty to collect
    state taxes. States would enforce their own taxes if Congress
    merely authorized them to tax, whereas they must rely on the
    federal government to do so under the PACT Act. Because this
    distinction may make all the difference under the Due Process
    Clause, the precedent on which Gordon relies does not resolve
    our constitutional question.
    Finding no conclusive precedent, we turn to first
    principles and there find support for Gordon’s argument that
    due process requires minimum contacts with the state or local
    government that defines the tax. 7 At its most basic level, “[t]he
    7
    My concurring colleague asserts that no court has “undertaken
    th[is] search before affirming the legitimacy of a tax.” Post, at 1
    (Sentelle, J., concurring). We need look no further than Quill to find
    an example of the Supreme Court returning to first principles to
    understand what type of “minimum contacts” serve to legitimate a
    state tax. See, e.g., Quill, 
    504 U.S. at 312
     (comparing the principles
    that animate the Due Process Clause with those that animate the
    Dormant Commerce Clause); see also New York ex rel. Cohn v.
    Graves, 
    300 U.S. 308
    , 312-13 (1937); Pollock v. Farmers’ Loan &
    Trust Co., 
    157 U.S. 429
    , 555-57 (1895), overruled by U.S. CONST.
    amend. XVI. It seems to me that this approach is to be encouraged
    when we are asked to apply existing law to novel cases. See, e.g.,
    FCC v. Fox TV Stations, Inc., 
    556 U.S. 502
    , 531-32 (2009) (Thomas,
    J., concurring) (criticizing the Court for not “looking to first
    principles to evaluate the constitutional question” when faced with
    novel fact patterns); Morse v. Frederick,

    constitutional doctrines without “returning to first principles”);

    131 S. Ct. 2780
    , 2789 (2011) (plurality opinion) (citations
    omitted). When it comes to the power to tax, the elements of
    “lawful power” are (1) “some definite link, some minimum
    connection, between a state and the person, property or
    transaction it seeks to tax,” and (2) a rational relationship
    between “the income attributed to the State for tax purposes”
    and “values connected with the taxing state.” Quill, 
    504 U.S. at 306

    We demand “minimum connections” because a taxation
    regime that does not rest on “minimum connections” lacks
    democratic legitimacy. See Quill, 
    504 U.S. at 312
     (“[T]he due
    process nexus analysis requires that we ask whether an
    individual’s connections with a State are substantial enough to
    legitimate the State’s exercise of power over him.”). The
    government would have us ignore the role of state and local
    governments in subjecting Gordon to their own tax laws, but it
    seems to me that the powers the states wield as a result of the
    PACT Act implicate the democratic principles that undergird

    433 U.S. 186

    can participate, at least through petitioning and speech, in the
    political process that decides whether it will. Cf. Borough of

    conduct, the decision to engage in that conduct is tantamount to
    consent to be taxed. Cf. Int’l Shoe Co. v. Washington, 
    326 U.S. 310
    , 318 (1945) (“[S]ome of the decisions holding the

    These principles give strength to Gordon’s argument that
    even a federal duty to comply with state and local tax laws may
    transgress due process limits on the taxation power. True
    enough, Gordon possesses minimum contacts with the federal
    government that will enforce his duty, but should we not also
    22
    demand that he possess minimum contacts with the state and
    local governments that will define his duty? The Framers saw
    the legislative process – which defines rather than enforces our
    duties – as the bulwark against oppressive taxation. 9 THE
    FEDERALIST NO. 35 (Alexander Hamilton) (“Is it not natural
    that a man who is a candidate for the favor of the
    people, . . . should be willing to allow them their proper degree
    of influence upon his conduct? This dependence, and the
    necessity of being bound himself . . . by the [taxes] to which he
    gives his assent, are the true, and they are the strong chords of
    sympathy between the representative and the constituent.”);
    THE FEDERALIST NO. 84 (Alexander Hamilton) (arguing that
    the people can rely on legislative accountability to ensure that
    legislatures do not exercise their taxing discretion to eliminate
    the freedom of the press). And the Supreme Court has long
    acknowledged the importance of this structural check. See
    McCulloch v. Maryland, 17 U.S. (4 Wheat.) 316, 428 (1819)
    (“The only security against the abuse of th[e] power [to tax], is
    found in the structure of the government itself. In imposing a
    tax the legislature acts upon its constituents. This is in general a
    sufficient security against erroneous and oppressive
    taxation.”); Int’l Harvester Co. v. Wisconsin Dep’t of Taxation,

    , 451 (1944) (Jackson, J., dissenting)
    (“Representation is the ordinary guaranty of fairness in
    taxation.”); Helvering v. Gerhardt, 
    304 U.S. 405
    , 415 (1938)
    (“State taxation of national instrumentalities is subject to no
    [democratic] restraint, for the people outside the state have no

    By focusing on enforcement alone, my dissenting colleague is
    missing an important piece of the picture. See post, at 2-3
    (Kavanaugh, J., dissenting). His preoccupation with the question of
    which government will hail Gordon into court obscures important
    distinctions between “the due process standards for adjudicative
    jurisdiction and those for legislative (or prescriptive) jurisdiction.”
    See Quill, 
    504 U.S. at 319-20
     (Scalia, J., concurring).
    23
    representatives who participate in the legislation; and in a real
    sense, as to them, the taxation is without representation.”).
    Without fair warning of which state and local legislatures will
    be constructing his tax burden, Gordon would lose a critical
    safeguard at the heart of democratic legitimacy. Gordon’s
    “minimum connection” with Congress affords him some
    security, to be sure, but it is not clear that his attenuated
    recourse to Congress to redress “erroneous or oppressive”
    taxes levied by state and local legislatures satisfies the Due
    Process Clause.
    ii
    Another “simple but controlling question” to test the
    lawfulness of an exercise of taxation power is “whether the
    state has given anything for which it can ask return.” See Nat’l
    Bellas Hess v. Dep’t of Revenue, 
    386 U.S. 753
    , 756 (1967)
    (internal quotation marks omitted); see also Quill, 
    504 U.S. at 306
    . Cf. New York ex rel. Cohn v. Graves, 
    300 U.S. 308
    , 313
    (1937) (“Enjoyment of the privileges of residence in the state
    and the attendant right to invoke the protection of its laws are
    inseparable from responsibility for sharing the costs of
    government.”). In order to protect this principle of just
    exchange, we uphold “the power of a state to impose liability
    on an out-of-state seller to collect a local use tax [when] the
    out-of-state seller was plainly accorded the protections and
    services of the taxing state.” Nat’l Bellas Hess, 
    386 U.S. at 757
    . When minimum contacts with the state or locality are
    present, the taxed party receives “the benefits and protections
    of the laws of [the] state,” Int’l Shoe Co., 
    326 U.S. at 319
    , and
    there is no due process problem with the state or locality
    extracting revenue from that party’s transactions. But when
    minimum contacts with that state or locality are lacking, the
    state or locality offers no services or protections to justify the
    tax it receives. Gordon may be correct that the due process
    24
    defects of this imbalanced exchange do not disappear simply
    because the federal government brokers it.
    In light of these principles, the district court did not abuse
    its discretion by concluding that Gordon is likely to succeed on
    this first step of his merits argument. In so holding, we caution
    that we are not deciding as a matter of law which sovereign a
    court must look to in completing its minimum contacts
    analysis. That question is one of significant moment, touching
    core federalism concerns. J. McIntyre Mach., Ltd., 
    131 S. Ct. at 2789
    . And as this discussion reveals, the PACT Act has been
    cast in a mold that has never been constitutionally tested. We
    are unwilling to resolve such an important and novel
    constitutional question without the benefit of further factual
    development.
    Before we may affirm the preliminary injunction,
    however, we must address the second constitutional question
    that informed the district court’s conclusion that Gordon is
    likely to succeed on the merits of his claim.
    2
    Under Section 2a of the PACT Act, Gordon’s obligation to
    collect a given state or local tax attaches when he initiates a
    transaction within that jurisdiction. Gordon’s due process
    challenge presents the question whether a single sale is enough
    to establish minimum contacts with that jurisdiction. The
    government asserts it is, providing a constitutional basis for the
    Act even if Gordon is correct that the Due Process Clause
    demands minimum contacts with the state or local taxing
    authority. Appellants’ Br. 30-33. Once again, the question is a
    close one, deserving of further development at a trial on the
    merits, so we affirm and remand. See Red Earth, 
    657 F.3d at 145
     (affirming a preliminary injunction against Section 2a of
    25
    the PACT Act on this ground and remanding for a trial on the
    merits).
    Due process jurisprudence on “minimum contacts” has
    evolved significantly over the past half-century. In National
    Bellas Hess v. Department of Revenue, the Supreme Court held
    that minimum contacts do not exist between a state and a seller
    “whose only connection with customers in the State is by
    common carrier or the United States mail.” 
    386 U.S. at 758
    ;
    see also Miller Bros. Co., 
    347 U.S. at 344-45
    . National Bellas
    Hess was commonly understood to require that the seller have
    some “physical presence” in the taxing state. Quill, 
    504 U.S. at 306-07
    . Thirty years later, in Quill, the Supreme Court
    overruled that holding. 
    Id. at 308
    . Relying on “comparable”
    reasoning in cases concerning the personal jurisdiction of
    courts, the Court concluded that North Dakota’s imposition of
    a duty to collect a use tax on Quill did not violate the Due
    Process Clause, even though Quill’s only contacts with citizens
    of North Dakota occurred by means of mail or common carrier.
    
    Id.
     The court relied on the fact that Quill purposefully directed
    its activities at residents of North Dakota, that it had conducted
    a high volume of business with customers in that state, and that
    the use tax was “related to the benefits Quill receives from
    access to the state.” 
    Id.
    But “[t]he Supreme Court has never found ‘that a single
    isolated sale . . . is sufficient’” to establish minimum contacts.
    Red Earth, 
    657 F.3d at 145
     (quoting J. McIntyre Mach., Ltd.,
    
    131 S. Ct. at 2792
     (Breyer, J., concurring)). While it may prove
    to be the case that, in the Internet age, a single sale establishes
    “minimum contacts” as a matter of law, this seems like
    precisely the sort of difficult constitutional question on which
    our analysis would benefit from factual development. For
    example, how difficult is it for a delivery seller to identify and
    calculate applicable taxes at the point of sale? What sorts of
    26
    services do states provide to delivery sellers (e.g., a forum for
    collecting debts from buyers, trash disposal for shipping
    cartons)? Without this knowledge, we find no reason to upset
    the district court’s reasonable conclusion that Gordon has
    demonstrated a likelihood of success on the merits of his due
    process challenge to the tax provisions of the PACT Act. We
    underscore that our analysis is preliminary; we make no final
    determination on the merits of Gordon’s due process
    challenge.
    B
    We likewise hold that the district court did not abuse its
    discretion in determining where the public interest lies when it
    concluded that “enforcement of a potentially unconstitutional
    law that would also have severe economic effects is not in the
    public interest.” Gordon, 826 F. Supp. 2d at 297.
    Relying upon United States v. Oakland Cannabis Buyer’s
    Coop., 
    532 U.S. 483
    , 497 (2001), the government argues that
    the court erred as a matter of law “by failing to give any
    deference to Congress’s assessment of where the public
    interest lies.” Appellants’ Br. 39. 10 In Oakland, the
    government invoked the Controlled Substances Act to enjoin
    the cooperative from distributing marijuana. Citing the “public
    interest,” the district court modified the injunction to permit
    distribution in cases of medical necessity. 
    532 U.S. at 495
    . The
    Supreme Court overturned the court of appeals decision
    affirming the modified injunction, holding that the district
    10
    The government also seeks support for this argument in Able
    v. United States, 
    44 F.3d 128
    , 131-32 (2d Cir. 1995). The
    government’s reliance on Able is misplaced. The cited holding
    relates not to the “public interest,” but to the “likelihood of success
    on the merits.” Id. at 130-31.
    27
    court’s considerable discretion to fashion equitable relief is
    bounded when it comes to deciding whether the “public
    interest” favors an injunction. Id. at 497. The district court
    could not “‘ignore the judgment of Congress, deliberately
    expressed in legislation’” by considering “any and all factors
    that might relate to the public interest.” Id. (quoting Virginian
    Ry. Co. v. Ry. Sys. Fed’n No. 40, Emps. Dep’t of the Am. Fed’n
    of Labor, 
    300 U.S. 515
     (1937)).
    The district court did not transgress the limits on its
    discretion here. Oakland prohibits a district court from
    second-guessing Congress’s lawful prioritization of its policy
    goals. 
    Id.
     For example, under the rationale of Oakland, it
    would have been wrong for the district court to hold that the
    public interest in preserving tobacco industry jobs outweighs
    the public health harms attributable to underage smoking. Such
    a holding would interfere with Congress’s “delegated powers”
    to “decide[] the order of priorities.” 
    Id.
     (internal quotation
    marks omitted). But the district court here did not second-guess
    Congress’s policy priorities – only the lawfulness of
    Congress’s means of achieving those priorities. In doing so, the
    court acknowledged the obvious: enforcement of an
    unconstitutional law is always contrary to the public interest.
    See, e.g., Lamprecht v. FCC, 
    958 F.2d 382
    , 390 (D.C. Cir.
    1992); G & V Lounge v. Michigan Liquor Control Comm’n, 
    23 F.3d 1071
    , 1079 (6th Cir. 1994); Llewlyn v. Oakland Cnty.
    Prosecutor’s Office, 
    402 F. Supp. 1379
    , 1393 (E.D. Mich.
    1975) (“[I]t may be assumed that the Constitution is the
    ultimate expression of the public interest.”). The Constitution
    does not permit Congress to prioritize any policy goal over the
    Due Process Clause.
    28
    C
    Finally, we hold that the district court did not abuse its
    discretion when it concluded that Gordon was likely to suffer
    irreparable harm and that the balance of the equities tips in his
    favor.
    Gordon argued that the PACT Act would cause him
    irreparable harm because it threatened the existence of his
    business and violated his constitutional rights. “[S]uits for
    declaratory and injunctive relief against the threatened
    invasion of a constitutional right do not ordinarily require
    proof of any injury other than the threatened constitutional
    deprivation itself.” Davis v. District of Columbia, 
    158 F.3d 1342
    , 1346 (D.C. Cir. 1998). Thus, “[a]lthough a plaintiff
    seeking equitable relief must show a threat of substantial and
    immediate irreparable injury, a prospective violation of a
    constitutional right constitutes irreparable injury for these
    purposes.” 
    Id.
     (internal citation omitted). The district court did
    not abuse its discretion by concluding that Gordon had
    demonstrated such a threat: when he was in business, the Act
    required Gordon to pay what he alleges are unconstitutional
    taxes or else risk criminal and civil penalties.
    Similarly, the district court concluded that “a potential
    deprivation of [Gordon’s] constitutional right to due
    process . . . outweighs the possible injury to defendants from
    enjoining enforcement until the merits of Gordon’s claim can
    be determined.” Gordon, 826 F. Supp. 2d at 297. Although the
    preliminary injunction might temporarily frustrate the federal
    government’s interest in enforcing state and local tax laws, the
    district court permissibly gave greater weight to the possibility
    that Gordon could suffer an ongoing constitutional violation
    while this litigation proceeds.
    29
    Now that Gordon’s business has ceased operations, he
    arguably no longer faces the dilemma on which the district
    court based its finding of irreparable injury. Neither does the
    government face the prospect of watching Gordon’s cigarette
    sales go untaxed. As the administrator of the injunction, the
    district court is better placed than we are to judge its ongoing
    necessity. Our charge in a § 1292(a)(1) appeal is limited to
    determining whether the district court acted within its
    discretion by issuing the preliminary injunction in the first
    instance. Finding no abuse of discretion, we decline the
    government’s invitation to vacate the injunction. In reaching
    that decision, we are sensitive to the gravity of enjoining an act
    of Congress, even temporarily. The government remains free
    to petition the district court for relief from the preliminary
    injunction in light of the changed circumstances. See FED. R.
    CIV. P. 60(b) (empowering the district court to “relieve a party”
    from an order).
    III
    Before we turn to the claims the district court dismissed,
    we must consider the government’s argument that the
    preliminary injunction is overbroad. The government argues
    that the injunction, which bars it from enforcing the tax
    provisions against Gordon at all, should have prohibited it only
    from enforcing the provisions against Gordon’s sales into
    jurisdictions with which he lacks minimum contacts. We hold
    that the district court adequately fulfilled its duty to “maintain
    the act in so far as it is valid.” Red Earth, 
    657 F.3d at 145
    (quoting Alaska Airlines, Inc. v. Brock, 
    480 U.S. 678
    , 684
    (1987)). By demanding that the injunction be narrower, the
    government asks the district court to put the cart before the
    horse. To accede to the government’s argument, the district
    court would not only have to define the much-disputed concept
    of “minimum contacts,” but would also have to engage in
    30
    significant fact-finding to determine where around the country
    Gordon has established minimum contacts. See Marcia Gordon
    Second Decl. ¶ 13 (“There are several states in which we have
    made zero or very few sales. In addition, there are many local
    jurisdictions in which we have never made a sale.”).
    Preliminary injunction hearings are ill-suited for such fine
    tailoring.
    More fundamentally, we are not convinced by the
    government’s premise: that Gordon may challenge the PACT
    Act only “as applied” against his sales into jurisdictions with
    which he lacks minimum contacts. The government points out
    that a court may find a statute to be invalid on its face only if a
    plaintiff has shown that the Act has no “plainly legitimate
    sweep.” Wash. State Grange v. Wash. State Repub. Party, 
    552 U.S. 442
    , 449 (2008) (citation omitted); see also United States
    v. Salerno, 
    481 U.S. 739
    , 745 (1987) (holding that facial
    challenges will be sustained only if “no set of circumstances
    exist under which the Act would be valid”). The government
    argues that any facial challenge to the PACT Act must fail
    because there is no dispute that the federal government may
    compel a delivery seller to collect taxes for at least those state
    and local governments with which it has minimum contacts.
    Thus, the Act has a “plainly legitimate sweep,” even if it
    sweeps too broadly.
    But when a statute erases the boundaries that define a
    sovereign’s jurisdiction, as the PACT Act does to the
    boundaries of state and local taxing jurisdictions, any
    legitimate application is pure happenstance. It is perhaps this
    consideration that has led the Supreme Court to sustain facial
    challenges to laws that omit constitutionally-required
    jurisdictional elements, even though all such laws necessarily
    have a “plainly legitimate sweep.” For example, in United
    States v. Lopez, the Supreme Court struck down the Gun-Free
    31
    School Zones Act of 1990, a federal law that prohibited
    individuals from knowingly possessing firearms within school
    zones. 
    514 U.S. 549
    , 551 (1995). The text of the statute
    “contain[ed] no jurisdictional element which would ensure,
    through case-by-case inquiry, that the firearm possession in
    question affects interstate commerce.” 
    Id. at 561
    ; see also
    United States v. Morrison, 
    529 U.S. 598
    , 613 (2000) (relying
    on Lopez to sustain a facial challenge to the Violence Against
    Women Act). Similarly, if Gordon’s due process analysis is
    correct, the PACT Act contains “no jurisdictional element
    which would ensure” that the taxes it imposes comport with the
    Due Process Clause. It permits state and local taxing powers to
    bleed over from legitimate objects of taxation to cover objects
    foreign to the state or local jurisdiction. Following the Supreme
    Court’s lead, we are not willing to hold – at the preliminary
    injunction stage – that Gordon is unable to maintain a facial
    challenge.
    IV
    We review de novo the district court’s dismissal of
    Gordon’s remaining claims. See Schrader v. Holder, 
    704 F.3d 980
    , 984 (D.C. Cir. 2013).
    A
    Gordon argues that Section 2a violates the Tenth
    Amendment by commandeering states to administer a federal
    taxation scheme. 11 The district court properly dismissed this
    Tenth Amendment challenge for failure to state a claim for
    11
    Gordon has standing to bring a claim that he was injured by
    Congress’s “disregard of the federal structure of our Government,”
    as reflected in the Tenth Amendment. See Bond v. United States, __
    U.S. __, 
    131 S. Ct. 2355
    , 2366-67 (2011).
    32
    relief. As the government points out, the type of burden the
    PACT Act creates is different in kind from the burdens the
    Supreme Court held to violate the Tenth Amendment in New
    York v. United States, 
    505 U.S. 144
     (1992), and Printz v.
    United States, 
    521 U.S. 898
     (1997).
    This is not a case in which “the Federal Government [is]
    compel[ling] the States to implement, by legislation or
    executive action, federal regulatory programs.” Printz, 
    521 U.S. at 925
    . Instead of drafting states to enforce federal law,
    the PACT Act pledges the federal government to enforce state
    law. See 
    15 U.S.C. § 377
     (imposing federal criminal penalties
    for violating the delivery sale provisions of the PACT Act).
    States may still craft their tax codes to accomplish their own
    policy goals. If a state wishes to increase tobacco consumption
    or to promote its use among minors, it retains the discretion to
    do so.
    In fact, the challenged provisions of the PACT Act do not
    direct the states to do anything. Any administrative burden that
    results is merely incidental to Congress’s lawful exercise of its
    power to regulate the private participants in interstate
    commerce. In New York, the Court left open the possibility that
    Congress could pursue permissible policy goals by directly
    regulating private parties rather than states. 
    505 U.S. at 159-60
    .
    That is what Congress has done here.
    The affirmative burdens placed on the states in Printz and
    New York were unavoidable. By contrast, states may avoid any
    burdens imposed by the PACT Act – a distinction the Supreme
    Court has treated as constitutionally significant. In FERC v.
    Mississippi, for example, the Court rejected a Tenth
    Amendment challenge to a federal statute that called for states
    to consider federal standards in regulating public utilities. 
    456 U.S. 742
     (1982). The Court emphasized that “if a State has no
    33
    utilities commission, or simply stops regulating in the field, it
    need not even entertain the federal proposals.” 
    Id. at 764
    ; see
    also Hodel v. Va. Surface Mining & Reclamation Ass’n, Inc.,
    
    452 U.S. 264
    , 288 (1981) (affirming a federal statute with
    similar reasoning). The Court in New York distinguished FERC
    v. Mississippi on these grounds, noting that there was nothing
    in the law at issue in FERC “directly compelling” the state to
    participate in the federal regulatory program. New York, 
    505 U.S. at 161-62
    ; see also Printz, 
    521 U.S. at 925-26
    . This case is
    much more like FERC than New York. If states wish to tax
    delivery sales of tobacco products, they may have to answer
    the federal call to accept pre-paid taxes from out-of-state
    sellers. Still, they may avoid that federal mandate altogether by
    not taxing tobacco delivery sales. Congress may lawfully
    present states with this Hobson’s choice because it has the
    power to prevent states from taxing interstate commerce
    altogether. See FERC, 
    456 U.S. at 759
    .
    Additionally, the PACT Act does not blur the lines of
    political accountability as did the statute challenged in New
    York, 
    505 U.S. at 169
    . Here, states still freely set the tax rates
    for which they may be held accountable. And because the Act
    applies directly to the sellers, it is clear that Congress is the
    source of the new duty, not the states. See United States v.
    Morrison, 
    529 U.S. 598
    , 654 n.21 (2000) (Souter, J.,
    dissenting) (“Had Congress chosen . . . to proceed instead by
    regulating the States, rather than private individuals, this
    accountability would be far less plain.”).
    The PACT Act regulates individuals, not states; its only
    incidental effect on the states is to require them to collect
    additional tax revenue if they choose to join Congress in
    regulating interstate commerce in tobacco products. This sort
    of burden is constitutionally permissible.
    34
    B
    The district court also properly dismissed Gordon’s Fifth
    Amendment challenge to the PACT Act’s ban on shipping
    tobacco products in the U.S. mail. Gordon argues that the ban
    deprives him of due process and the equal protection of the
    laws.
    There is no dispute that the district court properly applied
    rational basis review to the mail ban. Accordingly, Gordon has
    a claim only if he can show that there is no “rational
    relationship between [the ban] and some legitimate
    governmental purpose.” Am. Bus. Ass’n v. Rogoff, 
    649 F.3d 734
    , 742 (D.C. Cir. 2011) (citation omitted). This burden “to
    negative every conceivable basis which might support” the law
    is especially difficult to meet. FCC v. Beach Commc’ns, Inc.,
    
    508 U.S. 307
    , 315 (1993). Rational basis review “is not a
    license for courts to judge the wisdom, fairness, or logic of
    legislative choices.” 
    Id. at 313
    . Courts must uphold legislation
    “[e]ven if the classification involved . . . is to some extent both
    underinclusive and overinclusive . . . .” Vance v. Bradley, 
    440 U.S. 93
    , 108 (1979). In the ordinary case, “a law will be
    sustained if it can be said to advance a legitimate government
    interest, even if the law seems unwise or works to the
    disadvantage of a particular group, or if the rationale for it
    seems tenuous.” Romer v. Evans, 
    517 U.S. 620
    , 632 (1996).
    Gordon argues that this is no ordinary case because
    Congress has never before banned the shipment of a product
    that is legal in all fifty states and does not present a danger to
    the mail or mail carriers. Appellee’s Br. 47. Unprecedented
    laws, he asserts, are subject to more “careful” rational basis
    review under Romer v. Evans. Appellee’s Br. 50; see also
    Romer, 
    517 U.S. at 633
     (discussing the unprecedented nature
    of the law under review). We need not decide whether Romer
    35
    announced such a rule because the mail ban is not
    unprecedented. The government provides – and Gordon fails to
    distinguish – several examples of articles Congress has banned
    from the U.S. mail that are legal in all fifty states and do not
    present a danger to the mail or mail carriers. See, e.g., 
    39 U.S.C. § 3002
     (making vehicle master keys nonmailable); 
    id.
    § 3002a (making locksmithing devices nonmailable). We
    therefore examine this law as we examine any other law that
    does not infringe on a fundamental right or involve a suspect
    classification.
    Although we are by no means restricted to the stated
    reasons for passing a law in our search for a “rational basis,”
    Beach Commc’ns, 
    508 U.S. at 315
    , we need look no further
    than the statute itself to discern three rational bases for the mail
    ban. As we observed in Gordon I, Section 1 of the Act reveals
    that it was “aimed primarily at combating three evils: tobacco
    sales to minors, [illicit] cigarette trafficking, and
    circumvention of state taxation requirements.” 
    632 F.3d at
    723
    (citing Pub. L. No. 111-154, § 1(b)). Gordon does not dispute
    that these purposes are “legitimate governmental purposes,”
    but argues that the mail ban fails to advance them because it is
    duplicative, overinclusive in some ways, and underinclusive in
    others. His arguments ask us to engage in a higher level of
    scrutiny than rational basis review allows.
    For example, Gordon argues that Congress could have
    accomplished the goal of preventing illicit cigarette trafficking
    by enhancing penalties for violations of existing laws, rather
    than broadly excluding both licit and illicit tobacco deliveries
    from the mail. Once again, the legislative record reveals a
    rational basis for choosing one path over the other: delivery
    sellers “have been very successful at eluding traditional
    enforcement measures, by making their cigarette and
    smokeless tobacco deliveries by mail.” H.R. Rep. No. 111-117,
    36
    at 19 (2009). Our standard of review does not permit us to
    second-guess the wisdom of that choice.
    With respect to sales to minors, Gordon argues that the
    mail ban is duplicative because Congress promulgated age
    verification requirements in 15 U.S.C. § 376a(b)(4). Yet his
    next argument betrays an awareness that age verification
    requirements are only partially effective. He claims that the
    mail ban is underinclusive because it does not cover underage
    sales that occur at brick and mortar stores, which are also
    subject to age verification requirements. See Appellee’s Br. 54
    n.14 (citing Tobacco Free Kids Org., Where Do Youth Smokers
    Get Their Cigarettes?, http://www.tobaccofreekids.org/resear
    ch/factsheets/pdf/0073.pdf (last accessed June 7, 2013)). But
    Congress “must be allowed leeway to approach a perceived
    problem incrementally.” Beach Commc’ns, 
    508 U.S. at 316
    .
    Congress’s judgment that the existing enforcement
    mechanisms must be supplemented by the partial solution of a
    mail ban is entirely rational.
    Finally, Gordon argues that the mail ban is duplicative
    because the tax provisions already effectively prevent
    circumvention of state taxes. But as we note above, Congress
    concluded that the mail enables determined sellers to evade the
    law – including, presumably, the PACT Act’s command that
    sellers pay state and local taxes in advance of the sale. It is
    entirely rational for Congress to buttress other legal provisions
    by closing a popular channel for noncompliant commerce.
    Because Gordon has not met his high burden “to negative
    every conceivable basis” for the Act, Beach Commc’ns, 508
    U.S at 315, the district court was correct to dismiss Gordon’s
    claim. And because the only challenge to the mail ban was
    properly dismissed, we need not decide whether the district
    37
    court should have granted a preliminary injunction against the
    mail ban.
    V
    For the foregoing reasons, the district court’s decision is
    affirmed and the case is remanded for further proceedings
    consistent with this opinion.
    So ordered.
    KAVANAUGH, Circuit Judge, concurring in the judgment
    in part and dissenting in part: The majority opinion holds
    that key tax-related provisions of the Prevent All Cigarette
    Trafficking Act may be unconstitutional under the Due
    Process Clause’s minimum contacts principle. The majority
    opinion therefore affirms the District Court’s preliminary
    injunction barring the Federal Government from enforcing
    those provisions of the statute. I respectfully disagree. To
    obtain a preliminary injunction, a plaintiff must show, among
    other things, a likelihood of success on the merits. In my
    view, Gordon’s Due Process Clause claim lacks merit. I
    would therefore vacate the preliminary injunction entered by
    the District Court.
    In 2010, Congress passed and President Obama signed
    the Prevent All Cigarette Trafficking Act. That law requires
    cigarette sellers to comply with various state tax laws. The
    law was prompted by Congress’s finding that Internet
    cigarette sellers were not complying with federal, state, and
    local tax laws, resulting in billions of dollars in lost tax
    revenue each year.        Importantly for present purposes,
    violations of the Act are subject to federal criminal
    prosecution or federal civil suit. In such federal lawsuits, the
    United States is the relevant sovereign and jurisdiction. As I
    will explain, when the Federal Government (not a State)
    regulates a U.S. seller such as Gordon, there is no Due
    Process Clause minimum contacts issue.
    To begin, it is well-settled that Congress may enact
    federal laws that require sellers of a product to comply with
    certain state laws. So long as the federal law is otherwise
    justified under the Constitution – for example, as a Commerce
    Clause regulation of commercial activity – the fact that the
    federal law piggy-backs on state law in this fashion is
    irrelevant. The Supreme Court has long upheld federal laws
    of that sort. See Kentucky Whip & Collar Co. v. Illinois
    Central Railroad Co., 
    299 U.S. 334
     (1937); Clark Distilling
    2
    Co. v. Western Maryland Railway Co., 
    242 U.S. 311
     (1917).
    A number of federal laws follow that model. See, e.g., 
    7 U.S.C. §§ 1571
    , 1573 (no transfer of agricultural seeds into a
    State in violation of state law); 
    16 U.S.C. § 3372
    (a)(2) (no
    transfer of wildlife taken in violation of any state law); 
    18 U.S.C. §§ 842
    (c) (no transfer of explosives into a State where
    they are illegal under state law); 
    18 U.S.C. § 922
    (b)(2) (no
    transfer of firearms into a State where they are illegal under
    state law); 
    21 U.S.C. § 831
    (b) (online pharmacies must
    comply with the law of any State in which they do business or
    offer to do business); 
    31 U.S.C. § 5362
    (10)(A) (no online bets
    can be accepted where the bet is illegal in the State in which it
    is made); see also United States v. Kimbell Foods, Inc., 
    440 U.S. 715
    , 728 (1979) (“state law may be incorporated as the
    federal rule of decision”); Board of County Commissioners of
    the County of Jackson, Kansas v. United States, 
    308 U.S. 343
    ,
    351-52 (1939) (“the state law has been absorbed, as it were,
    as the governing federal rule not because state law was the
    source of the right but because recognition of state interests
    was not deemed inconsistent with federal policy”); Henry M.
    Hart, Jr., The Relations Between State and Federal Law, 54
    COLUM. L. REV. 489, 498 (1954) (“Congress rarely enacts a
    complete and self-sufficient body of federal law. The federal
    statutes are full of references, both explicit and implicit, to the
    law of some state.”) (footnote omitted).
    There is no dispute here that the relevant provisions of
    the Prevent All Cigarette Trafficking Act are valid under the
    Commerce Clause.        The question concerns the law’s
    compliance with the minimum contacts principle of the Due
    Process Clause.
    When Congress enacts a federal law of this kind and
    renders violators of that law subject to federal criminal
    prosecution or federal civil suit, the law does not violate the
    3
    minimum contacts principle of the Due Process Clause. The
    reason is quite simple: In such federal-law cases, the relevant
    sovereign and jurisdiction is the United States, not one of the
    individual States. There is no Due Process minimum contacts
    issue raised by a federal-law suit against a seller located in the
    United States. That was the conclusion reached by a three-
    judge District Court in this Circuit when it rejected a similar
    Due Process Clause minimum contacts challenge to the
    Jenkins Act. That Act required cigarette shippers to report
    out-of-state sales to the buyer’s state tobacco administrator.
    The Supreme Court summarily affirmed the Court’s decision.
    See Consumer Mail Order Association of America v.
    McGrath, 
    94 F. Supp. 705
    , 712 (D.D.C. 1950), aff’d, 
    340 U.S. 925
     (1951). I would reach the same conclusion here. See
    Musser’s Inc. v. United States, 
    2011 WL 4467784
    , at *5 (E.D.
    Pa. 2011) (denying preliminary injunction in Due Process
    Clause challenge to Prevent All Cigarette Trafficking Act).
    To be sure, a seller like Gordon may raise a Due Process
    Clause minimum contacts objection in any state-law
    proceeding. See Quill Corp. v. North Dakota, 
    504 U.S. 298
    (1992). But the Prevent All Cigarette Trafficking Act does
    not negate a seller’s ability to raise a Due Process Clause
    minimum contacts objection in state-law cases.
    In my view, therefore, Gordon’s Due Process Clause
    claim is entirely without merit. 1 To grant a preliminary
    injunction, however, a District Court must find a likelihood of
    success on the merits, among other things. See Winter v.
    Natural Resources Defense Council, 
    555 U.S. 7
    , 20 (2008)
    1
    The alternative Tenth Amendment argument advanced by
    Gordon in support of the preliminary injunction is likewise without
    merit, as the majority opinion explains and the District Court also
    concluded.

    that he is likely to succeed on the merits . . . .”); Munaf v.
    Geren, 
    553 U.S. 674
    , 690 (2008) (“a party seeking a
    preliminary injunction must demonstrate, among other things,
    a likelihood of success on the merits”) (internal quotation
    marks omitted); Davis v. Pension Benefit Guaranty Corp.,
    
    571 F.3d 1288
    , 1296 (D.C. Cir. 2009) (Kavanaugh, J.,
    concurring) (“In light of the Supreme Court’s recent
    decisions, I tend to agree . . . that the old sliding-scale
    approach to preliminary injunctions – under which a very
    strong likelihood of success could make up for a failure to
    show a likelihood of irreparable harm, or vice versa – is no
    longer controlling, or even viable. It appears that a party
    moving for a preliminary injunction must meet four
    independent requirements.”) (citation and internal quotation
    marks omitted); cf. Nken v. Holder, 
    556 U.S. 418
    , 438 (2009)
    (Kennedy, J., concurring) (“When considering success on the
    merits and irreparable harm, courts cannot dispense with the
    required showing of one simply because there is a strong
    likelihood of the other.”).
    When, as here, a District Court incorrectly finds a
    likelihood of success on the merits, that legal error constitutes
    an abuse of discretion, and we must vacate the preliminary
    injunction. See Kiyemba v. Obama, 
    561 F.3d 509
    , 513 (D.C.
    Cir. 2009) (“If the moving party can show no likelihood of
    success on the merits, then preliminary relief is obviously
    improper and the appellant is entitled to reversal of the order
    as a matter of law.”); Air Line Pilots Association International
    v. Eastern Air Lines, Inc., 
    863 F.2d 891
    , 894 (D.C. Cir. 1988)
    (“We reverse the district court and hold that it should not have
    granted the motions for a preliminary injunction because the
    unions did not show a substantial likelihood of success on the
    merits.”); see generally So v. Suchanek, 
    670 F.3d 1304
    , 1310
    (D.C. Cir. 2012) (“A district court by definition abuses its
    5
    discretion when it makes an error of law.”) (internal quotation
    marks omitted). 2
    Because Gordon’s Due Process Clause claim is meritless,
    I would vacate the District Court’s preliminary injunction
    against enforcement of the tax-related provisions of the Act.
    As to Gordon’s cross-appeal challenging the District Court’s
    denial of a preliminary injunction to enjoin enforcement of
    the Act’s mailing ban on Fifth Amendment grounds, I would
    affirm the District Court because Gordon has not shown a
    likelihood of success on the merits of that claim, for reasons
    the majority opinion explains.

    In certain First Amendment cases, the Supreme Court has
    said that a court of appeals may affirm a District Court’s
    preliminary injunction so long as the plaintiff has presented a
    “close” question on the merits. See Ashcroft v. ACLU, 
    542 U.S. 656
    , 664-65 (2004). But the “close” question standard is not the
    usual rule for preliminary injunctions or for appellate review of
    preliminary injunctions. And even if a close question were enough,
    Gordon has not presented a close question here.
    SENTELLE, Senior Circuit Judge, concurring in part and
    concurring in the judgment: I reluctantly concur in the result
    announced in Judge Griffith’s opinion. While this case may not
    be moot, it is not entirely clear what it is the parties are still
    litigating about, and I hope that the district court re-examines the
    mootness question with the benefit of a more full record.
    I do not join fully in Judge Griffith’s opinion because I
    think it opines on matters far beyond the issues before the court,
    and I do not wish to elevate those opinions to circuit law.
    First, footnote 1 of Judge Griffith’s opinion indulges, I think
    quite gratuitously, in a discussion of the effect of the so-called
    “Dormant Commerce Clause.” So far as I can tell, no party in
    this case relies upon the Dormant Commerce Clause, the
    Dormant Commerce Clause is not relied upon in the briefs, the
    Dormant Commerce Clause has nothing to do with the result,
    and this case has nothing to do with the Dormant Commerce
    Clause.
    Further, I cannot support Judge Griffith’s opinion in its test
    of “democratic legitimacy” for the minimum contacts necessary
    to provide due process for taxation. Griffith op. at 19 21. The
    search for democratic underpinnings for constitutional
    provisions may be academically interesting, but I find no case in
    which this court, the Supreme Court, or any other federal court
    has undertaken that search before affirming the legitimacy of a
    tax. Because Judge Griffith’s opinion supplies sufficient indicia
    of minimum contacts without relying on this novel approach, I
    join the result, indeed I join most of the opinion, but I cannot
    fully join the elevation to circuit law of a new test for minimum
    contacts, or of the discussion of the attributes of the “Dormant
    Commerce Clause.”
