Constitution of the State of Ohio Art. V, § 2a

The names of all candidates for an office at any election shall be arranged in a group under the title of that office.  The general assembly shall provide by law the means by which ballots shall give each candidate's name reasonably equal position by rotation or other comparable methods to the extent practical and appropriate to the voting procedure used.  At any election in which a candidate's party designation appears on the ballot, the name or designation of each candidate's party, if any, shall be printed under or after each candidate's name in less prominent type face than that in which the candidate's name is printed.  An elector may vote for candidates (other than candidates for electors of President and Vice President of the United States, and other than candidates for governor and lieutenant governor) only and in no other way than by indicating his vote for each candidate separately from the indication of his vote for any other candidate.
