Voters in 12 states could see abortion on their ballots this year, including three states where ballot measures have been certified for the ballot—Florida, Maryland, and New York. Measures have been proposed in nine other states. This report provides the most recent updates on abortion-related ballot measure certifications and potential measures.
On April 18, the campaign Coloradans for Protecting Reproductive Freedom submitted 230,000 signatures for a ballot initiative to provide a constitutional right to abortion in the state of Colorado. If the initiative makes the ballot in the state, it will be the tenth time that Colorado voters will decide on an abortion-related ballot measure—the most of any state. The last time Colorado voters decided on abortion was in 2014, when voters rejected an amendment that would have defined person to include a fetus or unborn human being.
Another Colorado campaign supporting an initiative that would have prohibited abortion in the state did not submit signatures to meet the deadline—proponents announced on April 18 that they did not gather enough signatures. This initiative would have defined living human child as a human being beginning at the moment of conception, and would have established penalties for individuals and facilities that perform abortions.
The next signature deadline for an abortion-related ballot initiative is on May 5, 2024, in Missouri, for an initiative that would provide a state constitutional right for reproductive freedom.
Here is the status of abortion-related ballot measures for 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, the Fairness Project, and Planned Parenthood of Southwest and Central Florida. On April 23, President Joe Biden (D) announced support for the measure.
- Measure opposition: Florida Voters Against Extremism is leading the campaign in opposition to the initiative. Opponents include Gov. Ron DeSantis (R), the Republican Party of Florida, 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) and Lt. Gov. Aruna Miller (D).
- 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, the New York Civil Liberties Union, and the Planned Parenthood Action Fund.
- Measure opposition: The Coalition to Protect Kids-NY is leading the campaign in opposition to the initiative. 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.

Pennsylvania
The Pennsylvania State Legislature may refer a constitutional amendment to the ballot that would say that the Pennsylvania Constitution grants no right to a taxpayer-funded abortion or any other right relating to abortion. The amendment already passed in the 2021-2022 legislative session and would need to pass the current session.
The Pennsylvania House of Representatives went from a Republican majority to a Democratic majority in the November 2022 election. The amendment would need 102 votes in the Pennsylvania House of Representatives to pass—there are 100 Republicans and 102 Democrats in the House. Previously, 106 Republicans and one Democrat voted for the amendment, and 88 Democrats and four Republicans voted against the amendment (with three Republicans absent for the vote).
