Provisional ballots are used in general elections when there is a question about a voter's eligibility at a polling station. Poll workers allow the person to vote with a provisional ballot until the problem is sorted out, and if the person is an eligible voter, then the ballot is counted.PolitiFact Ohio recently checked -- and rated as True -- the claim that Ohio has one of the highest provisional ballot rates in the country, and that many of those ballots go uncounted.
