A Missouri campaign is getting underway tied to Amendment 3, a measure on the November ballot that asks voters whether to roll back abortion rights approved in 2024.
The group Stop the Ban Missouri announced the launch of its “No on 3” campaign during a virtual press event Wednesday, arguing the measure could overturn protections added to the state constitution two years ago. Voters in 2024 approved an amendment that established a constitutional right to reproductive health care, including abortion.
Abortion Action Missouri spokesperson Maggie Olivia said she believes the use of the same amendment number could lead to confusion.
“They’re trying everything they can think of, pulling every trick out of their sleeve to try and muddy those waters,” Olivia said. “These politicians think that they can just overturn any vote they don’t like and play games with Missouri voters’ ballots.”
Margot Riphagen Dunn with Planned Parenthood said anti-abortion politicians have one goal.
“Making it impossible for Missourians to access abortion care in their own state,” Dunn said. “Voters across our state made history by clearly saying that personal medical decisions belong to patients, families, and providers, not to politicians.”
The proposed amendment was approved by the Republican-led Missouri Legislature in 2025 and placed before voters. The Missouri House passed the measure 103-51, with no Democrats supporting it.
The Missouri Senate later approved the proposal 21-11, largely along party lines, to send it to voters statewide.
Supporters of the measure say it gives voters a chance to revisit the issue. Republican lawmakers, including state Sen. Nick Schroer R-St. Charles and Sen. Rick Brattin R-Harrisonville, have said placing the measure on the ballot allows Missourians another opportunity to weigh in on abortion policy.
During Wednesday’s press event, a woman identified as Ashley shared her personal experience with pregnancy complications and the need for abortion care.
“My doctor and I sat together and quietly discussed a plan to travel out of state if I began to experience complications again,” she said. “Both of those (my current) children exist because I was able to get the abortion care that I needed when I needed it. But we know that that’s not everybody’s story.”
If approved by voters, Amendment 3 would repeal the constitutional protections adopted in 2024 and impose new limits on abortion with certain exceptions.
