NBC News projects the measure failed, and Just the News reports its defeat, citing the Associated Press. The results are unofficial.

The measure would have banned abortion except in a medical emergency, for fetal anomalies, or for rape or incest, NBC reports. In cases of rape or incest, abortion would have been allowed only up to 12 weeks.

A yes vote would have repealed the abortion rights amendment that Missouri voters narrowly approved in 2024, Just the News says.

Missouri was the first state to enforce an abortion ban after the Supreme Court overturned Roe v. Wade in 2022, NBC notes.

The measure also would have written a ban on gender transition procedures for minors into the constitution, the outlets report. A state law signed in 2023 already sets the same rules, NBC says.

Opponents raised more than $26 million in large donations this year, compared with about $6.7 million for supporters, Just the News reports.

Governor Mike Kehoe, who campaigned for the amendment, said its defeat would be “a sad day for Missouri,” according to Just the News.

Before the 2024 vote, a trigger law banned abortion with no exception for rape or incest, NBC reports. That law took effect right after the 2022 ruling.

Voters in Virginia also wrote a right to abortion into their state constitution, Just the News reports. Voters in 39 states decided 145 statewide measures on Tuesday, the site says.
