COLUMBUS (AP) — The Ohio Ballot Board allowed a proposal to proceed that would amend the state constitution to raise the minimum wage.

The amendment calls for annual boosts in the wage until it hits $13 an hour in 2025. The current Ohio minimum wage is $8.70 an hour. The board on Wednesday determined that the petition contains a single issue. That was the final step needed before backers could begin gathering signatures.

Supporters hope to put the amendment on the November ballot.

“There are workers around the state of Ohio who are ready to circulate these books immediately, just as soon as they’re printed off,” Anthony Caldwell, the public affairs director for SEIU District 1199, a union backing the campaign, told cleveland.com.

Ohio’s elections chief Frank LaRose and Senate President Larry Obhof, both Republicans, and state Rep. Paula Hicks-Hudson, a Democrat, are among the members of the five-person ballot board.
