Missouri abortion amendment

Amendment 3 supporters are emphasizing restrictions on gender-affirming care for minors — even though Missouri already bans most of it — as they seek to overturn the abortion rights that voters approved in 2024.

With a statewide vote on the line and national fights around mifepristone, the Missouri Abortion Fund has launched a campaign to remind Missourians they "always have options."

Some conservatives argue the abortion restrictions in Missouri Amendment 3 don’t go far enough, a split that could matter in a race that recent polling shows is essentially tied

Missouri is the only state voting this year on removing abortion protections already on the books.

The campaign to keep Missouri’s abortion rights amendment in place has so far outfundraised the campaign to reinstate a ban about 7 to 1, in part because of $5.3 million from the Fairness Project, a D.C.-based nonprofit that doesn’t have to disclose its donors.

If passed, Amendment 3 would repeal the abortion rights amendment enshrined in the Missouri Constitution in 2024. It would also add a constitutional ban on gender-affirming care for transgender youth in the state.

The statewide television and radio spot was developed with help from an anti-abortion medical group and will air through Sept. 30. It references a recent judge's ruling that struck down dozens of challenged abortion regulations as unconstitutional.

In November, Missourians will be asked whether they want to repeal the abortion rights amendment they approved in 2024 and reinstate an abortion ban. Unions and reproductive rights groups already worked together to defeat Amendments 4 and 5 in the August election.

Planned Parenthood clinics in Kansas City, Columbia and St. Louis restarted procedural abortions in 2025. All four clinics, along with the Planned Parenthood in Gladstone, also offer medication abortion.

The Stop the Ban campaign has raised more than $6.5 million. The leading political action committee on the other side, called Her Health, Her Future PAC, has raised just over $1 million as of last week.

Missouri residents overwhelmingly voted against proposals to eliminate the income tax and change how citizens can change the Missouri constitution. Meanwhile, Kansans elected Reverend Adam Hamilton as the Democratic opponent to U.S. Sen. Roger Marshall and Democrat Cindy Holscher and Republican Ty Masterson will face each other in the race for Kansas governor.
