For many of us, “voting” conjures an image of people going to a ballot box on Election Day, but the way voters submit ballots varies from state to state. Some have in-person voting, others have mail-in ballots. Some states allow early voting, and others have day-of voting only.
The Constitution sets some election rules, including the date of the general election, restrictions on voting rights, and the prohibition of poll taxes[1]. Congress can also pass laws to protect the right to vote, such as the Voting Rights Act of 1965, which prevents discriminatory practices like race-based voting restrictions, or the Uniformed and Overseas Citizens Absentee Voting Act, which allows overseas military personnel and other American citizens living abroad to vote. (These are two of six congressional voting laws.)
