Ohio Revised Code Title XXXV. Elections § 3513.20

Before any challenged person shall be allowed to vote at a primary election, the person shall make a statement, under penalty of election falsification, before one of the precinct officials, blanks for which shall be furnished by the board of elections, giving name, age, residence, length of residence in the precinct, county, and state; stating that the person desires to be affiliated with and supports the principles of the political party whose ballot the person desires to vote; and giving all other facts necessary to determine whether the person is entitled to vote in that primary election. The statement shall be returned to the office of the board with the pollbooks and tally sheets.

If a person challenged refuses to make that statement under penalty of election falsification, the person shall be permitted to vote a provisional ballot under section 3505.181 of the Revised Code. If a majority of the precinct officials finds that the statements of a person challenged or the person's voting record or other evidence shows that the person lacks any of the qualifications required to make the person a qualified elector at the primary election or that the person is not affiliated with or is not a member of the political party whose ballot the person desires to vote, the person shall be permitted to vote a provisional ballot under section 3505.181 of the Revised Code.
