opinion: PeR Curiam.
  This action was brought before a three-judge court convened in the Northern District of Illinois under 28 U. S. C. § 2281 and § 2284. The object of the action is an injunction against the enforcement of a provision which, in 1935, was added to a statute of Illinois and which requires that a petition to form and to nominate candidates for a new political party be signed by at least 25,000 qualified voters, “Provided, that included in the aggregate total of twenty-five thousand (25,000) signatures are the signatures of two hundred (200) qualified voters from each of at least fifty (50) counties within the State.” Ill. Rev. Stat. c. 46, § 10 — 2 (1947). Appellants are the “Progressive Party,” its nominees for United States Senator, Presidential Electors, and State offices, and several Illinois voters. Appellees are the Governor, the Auditor of Public Accounts, and the Secretary of State of Illinois, members of the Boards of Election Commissioners of various cities, and the County Clerks of various counties. The District Court found want of jurisdiction and denied the injunction. 80 F. Supp. 725. Appellants invoke the jurisdiction of this Court under 28 U. S. C. § 1253.
  The action arises from the finding of the State Officers Electoral Board that appellants had not obtained the requisite number of signatures from the requisite number of counties and its consequent ruling that their nominating petition was “not sufficient in law to entitle the said candidates’ names to appear on the ballot.” The appellants’ claim to equitable relief against this ruling is based upon the peculiar distribution of population among Illinois’ 102 counties. They allege that 52% of the State’s registered voters are residents of Cook County alone, 87 % are residents of the 49 most populous counties, and only 13% reside in the 53 least populous counties. Under these circumstances, they say, the Illinois statute is so discriminatory in its application as to amount to a violation of the due-process, equal-protection, and privileges- and-immunities clauses of the Fourteenth Amendment, as well as Article I, §§ 2 and 4, Article II, § 1, and the Seventeenth Amendment of the Constitution of the United States.
  It is clear that the requirement of two hundred signatures from at least fifty counties gives to the voters of the less populous counties of Illinois the power completely to block the nomination of candidates whose support is confined to geographically limited areas. But the State is entitled to deem this power not disproportionate: of 25,000 signatures required, only 9,800, or 39%, need be distributed; the remaining 61% may be obtained from a single county. And Cook County, the largest, contains not more than 52% of the State’s voters. It is allowable State policy to require that candidates for state-wide office should have support not limited to a concentrated locality. This is not a unique policy. See New York Laws 1896, c. 909, § 57, now N. Y. Elec. Law § 137 (4); 113 Laws of Ohio 349, Gen. Code § 4785-91 (1929), now Ohio Code Ann. (Cum. Supp. 1947) §4785-91; Mass. Acts, 1943, c. 334, § 2, now Mass. Ann. Laws c. 53, § 6 (1945). To assume that political power is a function exclusively of numbers is to disregard the practicalities of government. Thus, the Constitution protects the interests of the smaller against the greater by giving in the Senate entirely unequal representation to populations. It would be strange indeed, and doctrinaire, for this Court, applying such broad constitutional concepts as due process and equal protection of the laws, to deny a State the power to assure a proper diffusion of political initiative as between its thinly populated counties and those having concentrated masses, in view of the fact that the latter have practical opportunities for exerting their political weight at the polls not available to the former. The Constitution — a practical instrument of government— makes no such demands on the States. Colegrove v. Green, 328 U. S. 549, and Colegrove v. Barrett, 330 U. S. 804.
  On the record before us, we need not pass upon purely local questions, also urged by appellants, having no federal constitutional aspect.
  Judgment affirmed.
  Mr. Justice Rutledge.
  In its facts and legal issues this case is closely analogous to Colegrove v. Green, 328 U. S. 549. It presents serious constitutional questions crucial to the validity of Illinois election procedures and their application to the imminently impending general election. That a bare majority of this Court resolve them one way and three others hold opposing views only emphasizes their substantial character and supreme importance. These qualities are not diminished by the fact that the Attorney General of Illinois, appearing for the three members of the so-called “State Certifying Board,” has conceded in his brief the validity of appellants' position and at the bar of this Court has confessed error in the decision of the District Court. Nor is it insignificant or irrelevant that the application of the statutory procedures made by the state officials in practical effect denies to a substantial body of qualified voters the right to exercise their suffrage in behalf of candidates of their choice.
  Forced by the exigencies of their situation, appellants have invoked federal equity jurisdiction in vindication of their rights. They seek injunctive relief, in effect, to compel placing the names of their candidates upon the ballot for the general election to be held on November 2. For present purposes we may assume that appellants have acted with all possible dispatch. Even so, we find ourselves confronted on the eve of the election with the alternatives of denying the relief sought or of directing the issuance of an injunction.
  This choice, in my opinion, presents the crucial question and the only one necessarily or properly now to be decided. Beyond the constitutional questions it poses delicate problems concerning the propriety of granting the relief in the prevailing circumstances. Even if we assume that appellants’ constitutional rights have been violated, the questions arise whether, in those circumstances, the equity arm of the. federal courts can now be extended to give effective relief; and whether the relief, if given, might not do more harm than good, might not indeed either disrupt the Illinois election altogether or disfranchise more persons than have been disfranchised by the application of the questioned Illinois procedures.
  Every reason existing in Colegrove v. Green, supra, which seemed to me compelling to require this Court to decline to exercise its equity jurisdiction and to decide the constitutional questions is present here. See the opinion concurring in the result, 328 U. S. at 564. Indeed the circumstances are more exigent and therefore more compelling to that conclusion.
  We are on the eve of the national election. But twelve days remain. Necessarily some of these would be consumed in remanding the cause to the District Court and in its consideration, formulation and issuance of an injunction in essentially specific terms. The ballots, as certified by the state officials, are in process of printing and distribution. Absentee ballots have been distributed. Illinois is one of the more populous states. Millions of ballots will be required, not only in the state but in Cook County alone. It is true that, on the short record before us and in the necessarily brief time available for preparing both the record and the briefs, appellees who oppose granting the relief have not made an absolutely conclusive factual showing that new ballots, containing the names of appellants’ candidates, could not possibly be printed and distributed for use at the election. But they suggest with good reason that this could not be done. The task would be gigantic. Even with the mobilization of every possible resource, it is gravely doubtful that it could be accomplished. The risk would be very large that it could not be done. Even if it could for all except absentee voters, they would be disfranchised. Issuance of the injunction sought would invalidate the ballots already prepared, including the absentee ballots, and those now in course of preparation.
  The sum of these considerations, without regard to others not now necessary to state, forces me to conclude that the relief sought could be had at this late stage in the electoral process only at the gravest risk of disrupting that process completely in Illinois or of disfranchising Illinois voters in perhaps much greater numbers than those whose interests appellants represent. That is a risk which, in my judgment, federal courts of equity should not undertake and indeed are not free to undertake within the historic limits of their equity jurisdiction.
  Accordingly, I express no opinion concerning the constitutional and other questions presented. As in Colegrove v. Green, supra, I think the case is one in which, for the reasons stated, this Court may properly, and should, decline to exercise its jurisdiction in equity. Accordingly, but solely for this reason, I agree that the judgment refusing injunctive relief should be affirmed.
  The State Certifying Board is composed of the Governor, the Auditor of Public Accounts and the Secretary of State, and petitions for the formation of new state-wide political parties are filed with this board. (Ill. Rev. Stat. c. 46 [1947] §§ 10 — 2, 10 — 4.) On the filing of timely objection to such petitions, the certifying board transmits the petitions and the objections to the State Officers Electoral Board, which is not a party to this action. After passing on the objection, the State Officers Electoral Board informs the State Certifying Board of its ruling, and the certifying board is required to “abide by and comply with the ruling so made to all intents and purposes.” (Ill. Rev. Stat. c. 46 [1947] § 10 — 10.) Where objection is not made, or where it is made and overruled, the new party and the names of its candidates are certified by the State Certifying Board to the several county clerks; the clerks or the local boards of election commissioners, both groups being parties to this action, thereupon are required to print ballots containing the names of the candidates thus certified. (Ill. Rev. Stat. c. 46 [1947] § 10 — 14.)
