(COLUMBUS, Ohio) — Ohio residents this week began voting on a constitutional amendment whose fate will ultimately determine abortion access in the state.

Voters are considering two ballot initiatives; ballots began being accepted on Wednesday and go through Election Day on Nov. 7.

The two measures are: Issue 1, the amendment that if approved would add abortion rights to the state constitution; and Issue 2, which would legalize recreational marijuana.

The proposed abortion amendment would establish an “individual right to one’s own reproductive medical treatment including but not limited to abortion” and then creates legal protections for those individuals, among other guarantees like for contraception and fertility treatment.

The marijuana measure, if passed, would make Ohio the 24th state to legalize cannabis and would allow adults 21 years and older to buy and possess up to 2.5 ounces of flower and 15 grams of extract.

In August, Ohio voters resoundingly rejected a contentious, Republican-backed ballot measure that would have raised the threshold for future changes to the state constitution — an effort that would have specifically made it more difficult for the abortion amendment to pass.

When the U.S. Supreme Court struck down its previous Roe v. Wade ruling, in 2022, the justices returned the question of abortion access to individual states. Since then, while some states have largely ceased abortion access, others have taken up ballot measures that put the question before voters. In those cases — in both red and blue states so far — voters have rejected the potential for abortion restrictions and bans or elected to expand access.

On Sept. 27, the Ohio Supreme Court started hearing arguments about the state’s six-week abortion ban, which was previously put on hold by a lower court.

The success or failure of the abortion ballot measure could render that case moot, if state voters add abortion access to their constitution.

Both sides have built up mobilization efforts over the past few weeks — knocking on doors, canvassing and hosting rallies across the state.

“Whether you’re pro-life or pro-choice, Issue 1 just goes too far,” Ohio Gov. Mike DeWine, a Republican, said at a recent event at the Ohio GOP’s headquarters.

Ohio Democrats claimed last week to have been inching toward 100,000 doors knocked and more than 100,000 calls made in the time since their win in the August special election.

“We’re not leaving anything behind as we work to protect women’s rights to choose and prevent Ohio’s extreme abortion ban from taking effect,” Ohio Democratic Chairwoman Elizabeth Walters said during a recent press briefing.

There’s also been significant financial investment in the race. According to numbers from AdImpact released last week, $12.3 million had been spent or reserved in advertising around the abortion ballot measure, with anti-amendment groups outspending amendment supporters by about $1.6 million.

The two sides make their arguments

Both Ohioans United for Reproductive Rights, a coalition of groups supporting abortion rights, and allied Ohio Democrats have sounded the alarm on what they claim to be foul play by opponents of the abortion amendment.

Last month, the state Supreme Court allowed the Republican-controlled Ohio Ballot Board — which is overseen by Secretary of State Frank LaRose, who is also running for the U.S. Senate — to use amendment language that includes the phrase “unborn child.”

Democrats on the board had asked for measure’s language to remain what was on the petition that voters originally signed, which did not include that term.

Amendment supporters have argued it was rewritten to confuse voters and is misleading about what the measure would actually do.

“They’re running scared because they know their extreme abortion ban is wildly unpopular, and Ohio voters support a woman’s right to make medical decisions for themselves without interference from politicians,” Walters, with the state Democrats, said during a recent press call.

Abortion opponents have also attempted to broaden the stakes of the proposal, arguing that it “goes far beyond” codifying the protections of Roe v. Wade to potentially affect parents’ rights and “threaten the freedom of conscience of Ohio’s healthcare professionals and preclude … the enactment and enforcement of commonsense, protective laws,” as Protect Women Ohio, one of the leading organizations fighting against the amendment, wrote in a memo.

“The Abortion Amendment victimizes rather than protects and empowers women and girls,” they continued.

LaRose, a leading voice against the measure, said in a statement to ABC News that “as a father and someone who’s always stood up to protect life, I’ll be working to defeat this radical measure.”
