Yes, voters must present a form of ID showing a photo, or name and present address.
Without ID, a voter may cast a provisional ballot, which will be counted if he can present an ID within 10 days.
No excuse is required to mail in an absentee ballot.
Felons are prohibited from voting while in prison.
Voters may cast absentee ballots in person beginning 29 days before an election until the Monday before Election Day at 5 p.m. In 2014, Ohio passed a bill eliminating one week of early voting, during which voters could also register and cast a ballot on the same day. Secretary of State John Husted also issued a directive eliminating early voting on Sundays, all evening hours and the Monday before Election Day. After a federal court declared the directive unconstitutional, Husted issued a new directive in June adding two half days of Sunday voting and the Monday before Election Day until 2 p.m. Both policies were blocked by a federal court Sept. 4, which found that the cuts disproportionately impacted the right of African-American and low-income voters to cast their ballots. That decision was upheld by a federal appeals court on Sept. 24. On September 29, the U.S. Supreme Court issued a temporary stay of the lower court's ruling, allowing, at least for now, the early-voting cuts to stand. Husted then issued a final directive that removed one of the half Sundays, but will allow voters to go to the polls a half-day the Sunday before the election, and Monday before Election Day until 2 p.m.
