Certified abortion-related ballot measures in 2024
Colorado
Colorado voters will be deciding on a constitutional amendment that would provide a right to abortion in the state constitution. The initiative would prohibit the state or local governments from denying or impeding the right to an abortion and allow abortion to be a covered service under health insurance plans.
- Current law: Colorado is one of 10 states that does not restrict abortion after a specific point in a pregnancy. In 1984, Coloradans voted 50.4% to 49.6% to ban public funding of abortion except for cases where the mother’s life is in danger. The provision prevented state health insurance from covering abortions for government employees and others on state health insurance plans such as Medicaid. In 1998, Coloradans voted 55% to 45% to require parents to be notified if their minor children seek an abortion and voted 51% to 49% to reject a ban on partial-birth abortion.
- Measure type: Initiated constitutional amendment
- Measure support: Coloradans for Protecting Reproductive Freedom is leading the campaign in support of the initiative. The committee reported $4.48 million in contributions and $3.67 million in expenditures as of June 26, 2024. Supporters also include the Democratic Party of Colorado, the ACLU of Colorado, and the League of Women Voters of Colorado.
- Measure opposition: Pro-Life Colorado Fund and Vote No on 89 are leading the campaign opposing the initiative. Both committees collectively reported $1,396.79 in contributions and $214.59 in expenditures as of June 26, 2024. Opponents of the initiative include the organization March for Life.
- State political context: Colorado currently has a Democratic trifecta. In the previous presidential election in 2020, Joe Biden (D) won with 55.40% of the vote. Colorado has also seen more abortion-related ballot measures than any other state. There have been nine on the ballot since the first in 1984, and this year will increase that number to 10.
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 took 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. The campaign reported $38.27 million in contributions and $24.88 million in expenditures as of June 28, 2024. Supporters also include the ACLU of Florida, the League of Women Voters of Florida, the Fairness Project, and Planned Parenthood of Southwest and Central Florida. President Joe Biden (D) also announced support for the measure.
- Measure opposition: Florida Voters Against Extremism is leading the campaign in opposition to the initiative. The campaign reported $397,601.85 in contributions and $203,511.33 in expenditures as of June 28, 2024. Florida Freedom Fund, created by Florida Governor Ron DeSantis (R), registered to oppose the initiative as well as Amendment 3, the marijuana legalization initiative, and reported $121,400 in contributions. Opponents also include Attorney General Ashley B. Moody (R), the Republican Party of Florida, Susan B. Anthony Pro-Life America, the 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, though the committee has not reported any contributions. Supporters include Gov. Wes Moore (D) and Lt. Gov. Aruna Miller (D).

- Measure type: Citizen-initiated constitutional amendment

- State political context: Nevada currently has a divided government. The Republican Party controls the office of governor, while the Democratic Party controls both chambers of the state legislature. In the previous presidential election in 2020, Joe Biden (D) won with 50.06% 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.”

South Dakota
Constitutional Amendment G would provide a trimester framework for regulating abortion in the South Dakota Constitution. During the first trimester of pregnancy, the state would be prohibited from regulating a woman’s decision to have an abortion. During the second trimester of pregnancy, the state may regulate abortion, but “only in ways that are reasonably related to the physical health of the pregnant woman.” And during the third trimester of pregnancy, the state may regulate or prohibit abortion, except “when abortion is necessary, in the medical judgment of the woman’s physician, to preserve the life and health of the pregnant woman.”
- Current law: In South Dakota, abortion is banned except to save the life of the mother. Following the U.S. Supreme Court’s 2022 decision, a 2005 law passed by the South Dakota State Legislature went into effect.
