According to Secretary of State Husted:  In Ohio, you can vote by mail where absentee ballots are mailed to every voter in the state, almost 30 days of Early Voting, and then Election Day.

With absentee voting starting 28 days before the election, Ohio remains above the national average for access to voting. Many of our surrounding states – including Michigan, Kentucky, Pennsylvania and New York – don’t even provide an early voting option. In addition, with the exception of states that vote exclusively by mail, Ohio has been the only state to send absentee ballot applications to all voters ahead of the election.
