Voters in Arizona and 10 other states may decide on abortion in 2024, with confirmed abortion measures on the ballot in three—FL, MD, and NY


Voters in Arizona and ten additional states could be voting on proposed ballot measures related to abortion in 2024. Currently, there are three certified abortion-related ballot measures in Florida, Maryland, and New York.

Arizona for Abortion Access, the campaign gathering signatures to place an initiative on the ballot to provide a state constitutional right to an abortion, said supporters gathered at least 506,892 petition signatures as of April 2. In Arizona, at least 383,923 valid signatures are required to place a citizen-initiated constitutional amendment on the ballot. The campaign has until July 3 to submit signatures.

On April 9, 2024, the Arizona Supreme Court, in a 4-2 decision, upheld a law enacted in 1864 prohibiting abortion in most circumstances except to save the life of the mother. The law ordered prosecution for “a person who provides, supplies or administers to a pregnant woman, or procures such woman to take any medicine, drugs or substance, or uses or employs any instrument or other means whatever, with intent thereby to procure the miscarriage of such woman, unless it is necessary to save her life.”

As of April 9, abortion is legal for up to 15 weeks of pregnancy in Arizona. The Arizona Supreme Court stayed its ruling for 14 days.

Gov. Katie Hobbs (D) commented on the ruling and supported the proposed ballot initiative. She said, “To the people across Arizona who are concerned about the future of abortion rights in our state, who are worried about their bodily autonomy, who don’t want to see the freedoms of their wives, sisters and daughters restricted, you can make your two cents known at the ballot box, and I encourage you to do so.”

Cindy Dahlgren, the spokeswoman for the campaign opposing the initiative, It Goes Too Far, said, “Abortion is legal in Arizona up to 15-weeks and we have common sense safety precautions to protect girls and women. It’s reckless to lose those safety precautions just to expand abortion beyond what most voters support.”

Should the Arizona for Abortion Access campaign gather and submit a sufficient number of valid signatures to the state secretary by July 3, the amendment in question will be eligible to appear on the ballot for the November 5, 2024, election.

Below is the list of certified measures that will appear on the ballot, as well as potential measures that could appear on the ballot in 2024.

Certified abortion-related ballot measures in 2024

Florida

Amendment 4 would provide a constitutional right to abortion “before viability or when necessary to protect the patient’s health, as determined by the patient’s healthcare provider.”

  • Current law: On April 1, 2024, the Florida Supreme Court ruled that the state constitution’s right to privacy does not include the right to abortion, overturning a previous decision by the court in 1989 that found that the privacy clause provided a right to abortion. The ruling allowed the state’s 15-week abortion ban, passed by the legislature in 2022, to take effect. In 2023, the legislature passed another bill, called the Heartbeat Protection Act, to ban abortion at six weeks, which was contingent on the state supreme court overturning its prior ruling and allowing the 15-week ban to take effect. The six-week ban will take effect on May 1. Before 2022, abortions were legal in Florida until 24 weeks.
  • Measure type: Initiated constitutional amendment
  • Measure support: Floridians Protecting Freedom is leading the campaign supporting the initiative. Supporters include the ACLU of Florida, League of Women Voters of Florida, and Planned Parenthood of Southwest and Central Florida.
  • Measure opposition: Florida Voters Against Extremism is leading the campaign in opposition to the initiative. Opponents include Susan B. Anthony Pro-Life America, Florida Conference of Catholic Bishops, and the National Center for Life and Liberty.
  • State political context: Florida currently has a Republican trifecta. In the previous presidential election in 2020, Donald Trump (R) won with 51.22% of the vote.

Maryland

Maryland voters will be deciding a constitutional amendment that would guarantee a right to reproductive freedom, including the ability to prevent, continue, or end one’s own pregnancy. The ballot measure is designed to prohibit the constitutional right from being denied or infringed unless there is a compelling state interest, which would need to be achieved using the least restrictive means.

  • Current law: Currently, abortion is legal in Maryland until viability. Abortion is legal after viability if the woman’s life or health is endangered or there is a fetal anomaly.
  • Measure type: Legislatively referred constitutional amendment
  • Measure support: Freedom in Reproduction Maryland is leading the campaign supporting the amendment. Supporters include Gov. Wes Moore (D), Lt. Gov. Aruna Miller (D), the Maryland AFL-CIO, and the Maryland State Education Association.
  • Measure opposition: Health Not Harm MD is leading the campaign against the amendment. Opponents include the Maryland Catholic Conference, the Maryland Family Institute, and the Maryland Right to Life PAC.
  • State political context: Maryland currently has a Democratic trifecta. In the previous presidential election in 2020, Joe Biden (D) won with 65.36% of the vote.

New York

New York voters will decide on a constitutional amendment to prohibit the denial of a person’s rights based on the person’s “ethnicity, national origin, age, [and] disability,” as well as the person’s “sex, including sexual orientation, gender identity, gender expression, pregnancy, pregnancy outcomes, and reproductive healthcare and autonomy.” The measure was referred to the ballot by the New York State Legislature.

  • Current law: New York allows for an abortion up to 24 weeks of pregnancy. Abortion is permitted after 24 weeks if, as determined by a health care practitioner, the fetus is not viable or the pregnant woman’s life or health (including mental health) is at risk.
  • Measure type: Legislatively referred constitutional amendment
  • Measure support: New Yorkers for Equal Rights is leading the campaign to support the amendment. Supporters include Gov. Kathy Hochul (D), U.S. Sen. Kirsten Gillibrand (D), the League of Women Voters of New York, and the Planned Parenthood Action Fund.
  • Measure opposition: Opponents of the amendment include the New York State Catholic Conference.
  • State political context: New York currently has a Democratic trifecta. In the previous presidential election in 2020, Joe Biden (D) won with 60.87% of the vote.
