Main article: Voting rights in the United States
In the United States, suffrage is determined by the separate states, not federally (Wyoming being the first state to instill suffrage). However, the "right to vote" is expressly mentioned in five Amendments to the U.S. Constitution. These five Amendments limit the basis upon which the right to vote may be abridged or denied:
14th Amendment (1868): Regarding apportionment of Representatives.
15th Amendment (1870): "The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of race, color, or previous condition of servitude."
19th Amendment (1920): "The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of sex."
23rd Amendment (1961): provides that residents of the District of Columbia can vote for the President and Vice-President.
24th Amendment (1964): "The right of citizens of the United States to vote in any primary or other election for President or Vice President, for electors for President or Vice President, or for Senator or Representative in Congress, shall not be denied or abridged by the United States or any State by reason of failure to pay any poll tax or other tax."
26th Amendment (1971): "The right of citizens of the United States, who are eighteen years of age or older, to vote shall not be denied or abridged by the United States or by any State on account of age."
