Ballot Tracker:
Outcome of Abortion-Related State Constitutional Amendment Measures in the 2024 Election

Since the Supreme Court’s Dobbs decision overturning Roe v. Wade, voters in 6 states have weighed in on constitutional amendments regarding abortion, and the side favoring access to abortion prevailed in every state. In 4 of these states – California, Michigan, Ohio, and Vermont – measures amending the state constitution to protect the right to abortion were approved by voters and in the other 2 states – Kentucky and Kansas – measures seeking to curtail the right to abortion failed. In 2024, 10 states voted on abortion measures seeking to either affirm that the state constitution protects the right to abortion or that nothing in the constitution confers such a right. There are two routes a measure may be placed on the ballot: citizen initiative and legislative referral.

—Legislatively-referred measures are introduced and approved by lawmakers before they appear on the ballot for citizens to vote on.
—Citizen-initiated measures are written by citizen groups and are placed on the ballot if they receive enough signatures.
