<P> At the time of its creation, the Constitution did not explicitly give citizens an inherent right to vote . Rather, it provided that those qualified to vote in elections for the largest chamber of a state's legislature may vote in Congressional (House of Representatives) elections . Since the Civil War, several constitutional amendments have been enacted that have curbed the states' broad powers to set voter qualification standards . Though never enforced, clause 2 of the Fourteenth Amendment provides that "when the right to vote at any election for the choice of electors for President and Vice President of the United States, Representatives in Congress, the Executive and Judicial officers of a State, or the members of the Legislature thereof, is denied to any of the male inhabitants of such State, being twenty - one years of age, and citizens of the United States, or in any way abridged, except for participation in rebellion, or other crime, the basis of representation therein shall be reduced in the proportion which the number of such male citizens shall bear to the whole number of male citizens twenty - one years of age in such State ." The Fifteenth Amendment prohibits the denial of the right to vote based on race, color, or previous condition of servitude . The Nineteenth Amendment prohibits the denial of the right to vote based on sex . The Twenty - fourth Amendment prohibits the revocation of voting rights due to the non-payment of a poll tax . The Twenty - sixth Amendment prohibits the denial of the right of US citizens, eighteen years of age or older, to vote on account of age . </P> <P> Moreover, since the Supreme Court has recognized voting as a fundamental right, the Equal Protection Clause places very tight limitations (albeit with uncertain limits) on the states' ability to define voter qualifications; it is fair to say that qualifications beyond citizenship, residency, and age are usually questionable . </P> <P> In the 1960s, the Supreme Court started to view voting as a fundamental right covered by the Equal Protection Clause of the Fourteenth Amendment . In a dissenting opinion of a 1964 Supreme Court case involving reapportionment in the Alabama state legislature, Associate Justice John Marshall Harlan II included Minor in a list of past decisions about voting and apportionment which were no longer being followed . </P> <P> In Oregon v. Mitchell (1970), the Supreme Court held that the Qualifications clause did not prevent Congress from overriding state - imposed minimum age restrictions for voters in Congressional elections . </P>
