COLUMBUS, Ohio—A proposed Ohio constitutional amendment to award the state’s presidential electoral votes to the winner of the national popular vote has cleared an initial hurdle toward making the statewide ballot this November.

A summary of the proposed amendment was certified by Attorney General Dave Yost on Monday as a “fair and truthful statement of the proposed law,” though Yost didn’t weigh in on whether he supported or opposed the measure.

The proposed amendment now heads to the Ohio Ballot Board, which has 10 days to decide whether the submitted ballot language only contains one proposed constitutional amendment. If the board decides it does, supporters would then have until July 3 to collect 442,958 valid signatures from registered voters in at least 44 of Ohio’s 88 counties.

It’s not clear which group is behind the proposal, though the committee representing the petitioners includes Franklin County Democratic Party Executive Director Dan McKay and Ohio Democratic Women’s Caucus Secretary Carole DePaola, according to documents released by Yost’s office.

The proposed amendment was submitted to the attorney general’s office by Columbus election lawyer Don McTigue, along with 1,000 signatures of Ohio voters collected by a professional canvasser who listed a Washington, D.C. address.

However, when cleveland.com asked McTigue who was behind the effort, he referred comment to Reed Hundt, a former Federal Communications Commission chair who is now chair and CEO of Making Every Vote Count, a non-profit pushing for a binding national popular vote. Reached by phone, Hundt declined to comment Monday.

After Republican Donald Trump won the 2016 presidential election (and Ohio) despite losing the popular vote, many Democrats – including some presidential candidates – have called for abolishing the Electoral College and awarding the presidency to the candidate who wins the most votes nationwide.

Supporters say choosing a president via a national popular vote instead of the convoluted Electoral College is a matter of fairness. However, critics will be sure to mention that such a system would lessen the political clout of Ohio, a pivotal swing state in many recent presidential elections.

The proposed amendment is also opposed by the California-based group National Popular Vote, which is also seeking to create a binding national popular vote, but in a different way – a National Popular Vote Interstate Compact, under which individual states pledge to cast their electoral votes for the winner of the national vote.

“We are focused on efforts to get state legislatures to pass legislation to enact the National Popular Vote interstate compact,” said John Koza, chair of National Popular Vote, in an email.

So far, 11 states holding a combined 181 electoral votes have signed the compact. However, the compact doesn’t become binding until it’s joined by states representing at least 270 electoral votes (the minimum needed to win the presidency).

Ohio, which currently has 18 electoral votes, has so far not joined the compact. Legislation to do so was introduced earlier this year by state Rep. David Leland, a Columbus Democrat, but its chances of passage are iffy in the Republican-dominated legislature.
