Voters in seven states approve abortion-rights constitutional amendments on Election Day 2024, while measures fail in Florida, Nebraska, and South Dakota, the first such defeats since Dobbs

On November 5, 2024, voters in Arizona, Colorado, Maryland, Missouri, Montana, Nevada, and New York approved ballot measures adding abortion protections to their state constitutions, while similar measures failed in Florida, Nebraska, and South Dakota. Missouri produced the night's sharpest reversal: in a state with a near-total abortion ban, voters approved Amendment 3, a constitutional right to reproductive freedom, with about 52% of the vote, weeks after the Missouri Supreme Court ruled 4-3 to keep the measure on the ballot. Florida's Amendment 4 showed the limits of majority support: 57% of voters backed it, but Florida requires 60% approval for constitutional amendments, so the state's six-week ban stayed in effect. The night ended a streak in which the abortion-rights side had won all seven post-Dobbs ballot fights, beginning with Kansas in August 2022. It also brought to ten the number of states where voters have written abortion protections into their constitutions since Dobbs; Nevada's amendment counts only after a required second approval vote in 2026.
