Ohio constitution
Article V: elective franchise
Section 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.
