The issue of voting rights in the United States has been fought for throughout United States history. Eligibility to vote in the United States is established both in the US Constitution and its amendments, and by state law. 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.
