Voting rights in the United States
Eligibility to vote in the United States is established both through the United States Constitution and by state law. Several constitutional amendments (the Fifteenth, Nineteenth, and Twenty-sixth specifically) require that voting rights of U.S. citizens cannot be abridged on account of race, color, previous condition of servitude, sex, or age for those above 18; the constitution as originally written did not establish any such rights during 1787–1870, except that if a state permitted a person to vote for the "most numerous branch" of its state legislature, it was required to permit that person to vote in elections for members of the United States House of Representatives. In the absence of a specific federal law or constitutional provision, each state is given considerable discretion to establish qualifications for suffrage and candidacy within its own respective jurisdiction; in addition, states and lower level jurisdictions establish election systems, such as at-large or single member district elections for county councils or school boards. Beyond qualifications for suffrage, rules and regulations concerning voting (such as the poll tax) have been contested since the advent of Jim Crow laws and related provisions that indirectly disenfranchised racial minorities.
