Ohio voters enshrined abortion rights in their state’s Constitution, a boon for Democrats running on the issue and complicating Republicans’ campaign messages with the approach of the 2024 elections.

The amendment, known as Issue 1, was adopted by a margin of 59% to 41% with a third of the vote counted in Tuesday’s general election in Ohio, according to the Associated Press. It’s the only state with an abortion issue on the ballot this fall. The amendment prevents the state from interfering with reproductive decisions up to about 23 weeks of pregnancy.
