History of Ohio constitution amendment votes

Amendments to Ohio's constitution can be proposed by a Constitutional Convention (which is rare), a joint resolution by the General Assembly (most common) or a citizen petition, and voters then cast ballots on the proposed amendments.

Since 1913, Ohio citizens have faced 225 votes on possible changes to the Ohio constitution, and they have passed barely more than half (53.8 percent).
