COLUMBUS, Ohio—Ohio’s 18 presidential electoral votes would be awarded to the candidate who wins the national popular vote, under a proposed state constitutional amendment that cleared an initial hurdle Monday.

Here are three takeaways:

- Backers include Franklin County Democratic Party Executive Director Dan McKay and Ohio Democratic Women’s Caucus Secretary Carole DePaola.

- Attorney General Dave Yost certified an amendment summary, sending the measure to the Ohio Ballot Board.

- If it passes the Ballot Board, supporters would have until July 3 to collect 442,958 valid signatures from registered voters to place the measure on the November ballot.
