Missouri voters reject Amendment 3, keeping abortion rights in the constitution

Missouri voters on Tuesday rejected Amendment 3, a measure that would have banned nearly all elective abortions in the state constitution, according to projections by Decision Desk HQ and NBC News ¹². The amendment won only 44% of the vote ³.

The defeat leaves in place the constitutional right to abortion up to the point of fetal viability that voters approved in 2024, when 51.6% backed a citizen-led reproductive rights measure ³. Missouri had been the first state to enforce an abortion ban after the Supreme Court overturned Roe v. Wade in 2022, through a trigger law that took effect immediately and banned abortion with no exception for rape or incest ².

Amendment 3 would have allowed abortion only in cases of medical emergency, fetal anomaly, or rape or incest within the first 12 weeks of pregnancy ². It also would have placed a constitutional ban on gender-affirming care for minors, including hormone therapy and puberty-blocking drugs ²³. A state law signed in 2023 by then-Gov. Mike Parson already imposes those restrictions; the statutory ban on puberty blockers and cross-sex hormones is scheduled to expire in 2027, while the prohibition on gender-affirming surgeries for minors is permanent ²³.

The measure was put forward by Republican lawmakers who hoped a second vote would undo the 2024 result ¹. The state's first lady, Claudia Kehoe, served as treasurer for the campaign to pass it, and Gov. Mike Kehoe campaigned across Missouri for Amendment 3 on Monday ¹³. The campaign, Her Health, Her Future, raised more than $7 million but was significantly outspent by abortion rights advocates; the Stop the Ban coalition had raised more than $27 million ahead of Election Day ³.

Backers focused heavily on gender-affirming care for minors. Tom Estes, a Republican state Senate staffer working on the pro-Amendment 3 campaign, told The 19th earlier this year that several elements of the measure resonated well and that they may not have gotten them last time, with the trans issue being the number one piece.

After the result, Estes struck a defiant note. "We came up short today, but this is a battle in a war, and so we are definitely going to keep on going forever," he told reporters in Columbia ³.

Abortion rights supporters celebrated in St. Louis. "Politicians thought they knew better than voters," said Dr. Margaret Baum, chief medical officer of Planned Parenthood Great Rivers ³. Mallory Schwarz, executive director of Abortion Action Missouri, said the coalition had fought for 18 months to protect "our fundamental rights to our own bodies, lives and futures" ³.

The outcome is a setback for a movement that had pointed to Missouri as a national model. David Bereit, executive director of the Virginia-based Life Leadership Conference, said at a virtual fundraising event in October that if the measure lost, "no other state will likely try this again for a long time, perhaps for a generation" ³.

That matters because Missouri is now the first state to defeat an attempt to overturn an abortion rights measure, and the first to reject a constitutional ban on gender-affirming care for minors ³. Abortion access in the state remains limited: five of Missouri's Planned Parenthood clinics have resumed providing the procedure amid ongoing litigation over restrictions found unconstitutional under the 2024 amendment ³.
