Voters in 10 states are deciding on ballot measures in the 2024 election that would enshrine abortion rights. That is the most in one election since the since the Supreme Court overturned Roe v. Wade two years ago. Going into the election, half of those states had banned abortion throughout pregnancy, or after six, 12 or 15 weeks. Nebraska has two competing ballot measures, one that would protect the right to an abortion until fetal viability and another that would ban it after the first trimester.

Florida (Failed)

A yes vote on the citizen initiative would amend the state’s constitution to protect abortion rights until fetal viability and to protect the health of the patient.

Threshold to pass: 60% or more of votes

Missouri

A yes vote on the citizen initiative would prevent the government from restricting a person’s fundamental right to reproductive freedom, including abortion until fetal viability or to protect the health of the pregnant patient.

Threshold to pass: 50% or more of votes

South Dakota

A yes vote on the citizen initiative would amend the state constitution to establish a constitutional right to an abortion in the first trimester but allow restrictions later in pregnancy.

Threshold to pass: 50% or more of votes

Nebraska

Nebraska has two measures. To pass, a measure would need a majority of votes in support and at least 35% of the total ballots cast in Nebraska to be in its favor.

If both pass, the measure with the most votes in favor would win pending a decision from the governor on whether the two conflict enough to bar from taking effect. Nebraska’s secretary of state has said the two measures conflict with another and couldn’t both be in effect simultaneously.

A spokeswoman for Nebraska Gov. Jim Pillen declined to comment on “speculative hypotheticals” ahead of the election.

A for vote on citizen-led Initiative 434 would ban abortion after the first trimester except in medical emergencies or if the pregnancy is the result of sexual assault or incest.

A for vote on citizen-led Initiative 439 would amend the state constitution to provide a right to abortion until fetal viability or to protect the health of the patient.

Arizona

A yes vote on the citizen initiative would amend the state constitution to protect abortion rights until fetal viability, or roughly 23 weeks of pregnancy, and to protect the health of the pregnant patient.

Threshold to pass: 50% or more of votes

Montana

A yes vote on the citizen initiative would amend the state’s constitution to expressly provide a right to abortion until fetal viability or to protect the health of the patient.

Threshold to pass: 50% or more of votes

New York

A yes vote on the legislatively referred measure would establish broad equal-rights protections, including for pregnancy and reproductive healthcare, that supporters say would make laws restricting abortions unconstitutional.

Threshold to pass: 50% or more of votes

Nevada

A yes vote on the citizen initiative would place the question on the ballot in 2026. Two votes approving the initiative in back-to-back general elections would amend the state constitution to provide the right to abortion from a qualified healthcare practitioner until fetal viability or to protect the health of the patient.

Threshold to pass: 50% or more of votes

Colorado

A yes vote on the citizen initiative would amend the state constitution to protect abortion rights and repeal a section that limited health-insurance coverage for abortion.

Threshold to pass: 55% or more of votes

Maryland

A yes vote on the legislatively referred measure would guarantee a fundamental right to reproductive freedom, including the right to terminate one’s own pregnancy.

Threshold to pass: 50% or more of votes
