Abortion Ballot Initiatives: State Updates Post-Dobbs (2026)
Missouri voters will decide in November whether to enshrine abortion rights in the state constitution, marking the latest battleground in the ongoing fight over reproductive access following the Supreme Court’s 2022 Dobbs v. Jackson Women’s Health Organization decision. The measure, initiated by citizen petition, comes after a flurry of state-level votes on abortion access since the overturning of Roe v. Wade.
The Dobbs decision, which eliminated the federal constitutional right to an abortion, immediately triggered a near-total ban in Missouri, enacted through a previously existing “trigger law.” According to a primer published by Sidney Watson and SLU LAW student Mary Quandt, Missouri’s criminal laws regarding abortion were swiftly impacted by the ruling. The state was the first in the nation to enact such a ban, as reported by STLPR on the two-year anniversary of the Dobbs decision.
Since 2022, seventeen states have seen ballot measures related to abortion. In 2024 alone, ten states voted on measures seeking to protect abortion rights through constitutional amendments. Seven of those – Arizona, Colorado, Maryland, Montana, Nevada, New York, and Missouri – succeeded in passing those amendments. Nebraska voters approved a measure banning abortions after the first trimester, while similar efforts failed in Florida and South Dakota. Prior to 2024, California, Michigan, Ohio, and Vermont voters had already approved measures protecting abortion rights.
Ballot initiatives can be placed before voters in two primary ways: through legislative referral, where lawmakers approve a measure for the ballot, or through citizen initiative, where citizen groups gather enough signatures to qualify a measure. Not all states allow citizen-initiated measures.
The Missouri measure currently on the ballot requires a simple majority to pass. If approved, it would establish a state constitutional right to abortion, preventing the state from interfering with reproductive healthcare decisions. The campaign to place the initiative on the ballot, spearheaded by a coalition of reproductive rights groups, gathered over 390,000 signatures, exceeding the required threshold.
Beyond Missouri, voters in Nevada and Virginia will also weigh in on abortion-related measures this November. Idaho and Nebraska are currently in the process of collecting signatures for potential ballot initiatives. The landscape of these initiatives is constantly evolving, as detailed in a recent brief from KFF, which provides further background on abortion-related ballot initiatives.
The outcomes of these votes are expected to have significant implications for abortion access in those states, potentially reshaping the legal landscape for millions of women. The Missouri measure, in particular, is being closely watched as a test case for the effectiveness of citizen-led initiatives in restoring abortion rights in the post-Roe era.
