BREAKING UPDATE: Ohio voters have chosen to enshrine abortion access with certain restrictions within the state constitution, NewsNation / Decision Desk HQ projects. Ohio is the fourth state in the country and the first swing state to do so.

Original story: (NewsNation) — Voters head to the polls in Ohio Tuesday to decide whether to enshrine abortion protections into the state constitution. If passed, Ohio would become the fourth state to do so in the country.

Polls close in Ohio at 7:30 p.m. ET. As results are reported, the map below will be updated.

State Issue 1 would grant pregnant people the constitutional right to “make and carry out one’s own reproductive decisions” about abortion, contraception, fertility treatment, continuing pregnancy and miscarriage care.

It would undo a 2019 law banning abortion after six weeks of pregnancy with no exceptions for cases of rape or incest. The law has been blocked by the state’s courts since being enacted, leaving abortion currently legal through 22 weeks.

The effort to protect reproductive rights in the state constitution comes as abortion has been outlawed in a number of states, leaving large swathes of the country where people cannot terminate a pregnancy. The Supreme Court’s decision to overturn Roe v. Wade created a patchwork of access to care, with some states expanding access to reproductive health while others passed laws strictly limiting or virtually outlawing the procedure.

For Ohioans, it is the second time this year abortion will be a motivating factor at the polls. Voters in August rejected a constitutional amendment — introduced as a measure to make the abortion issue harder to pass in November — that would have raised the threshold for such measures to pass from a simple majority to 60% support.

While State Issue 1 would grant protections for reproductive health care broadly, it would still allow the state to pass laws regulating abortion after the point of fetal viability as long as exceptions were made for the life or health of the mother. Fetal viability is the point at which a fetus is likely to survive outside of the womb and is generally thought to occur around the 24th week of pregnancy.

Last year, abortion rights advocates saw success in red states including Kansas, Kentucky and Montana. Those wins, however, were achieved by rejecting anti-abortion measures, not approving protections.

How Ohio voters decide could also have implications for the 2024 election, with the swing state providing a potential bellwether of how voters feel about abortion in a post-Roe world.
