Map: Tracking abortion-related ballot measures in the upcoming election

Nearly two years after Roe v. Wade was overturned, 14 states have passed total abortion bans while others have moved to protect reproductive rights at the state level.

Most recently, the U.S. Supreme Court threw out a challenge to the widely used abortion pill mifepristone. The ruling upholds how the U.S. Food and Drug Administration regulates the abortion pills, allowing them to be mailed to patients.

The decision marked a significant moment in the abortion rights battle, as nearly two-thirds of abortions in the U.S. last year were done through medication, according to the Guttmacher Institute, a research and policy organization focused on reproductive rights.

With the November general election a few months away, residents in Colorado, Maryland, South Dakota and Florida will be able to vote on ballot initiatives related to abortion access. Another six states are in the process of approving the initiatives.

Here's the status of abortion-related state ballot measures in the upcoming November election:

Tracking the status of abortion-related ballot measures

Within the last two years, residents in seven states have voted to further protect reproductive rights or uphold access abortion on ballot measures. They are: California, Kansas, Kentucky, Michigan, Montana, Ohio and Vermont.

Legislators in Wisconsin, Louisiana and Maine worked toward adding abortion-related measures to the ballot in November, but failed to get approval.

Colorado

In Colorado, voters will decide during the upcoming November election whether to enshrine abortion rights into the state constitution. The ballot initiative – certified by the Colorado secretary of state in May – would further ensure future legislative efforts will not restrict it. 

Abortion access is already protected in the state of Colorado.

Florida

The Florida Supreme Court allowed a ban on abortions after six weeks earlier this year. It also certified language for a ballot measure aiming to protect reproductive rights in the state constitution.

Florida voters will decide whether to adopt Amendment 4 during the upcoming November election. If the ballot initiative is adopted, access to abortion up to fetal viability would become a constitutional right, overturning the current six-week ban.

Maryland

Marylanders will have the opportunity to enshrine access to abortion in the state constitution this November. A ballot measure will be included in the upcoming presidential election.

The Maryland Right to Reproductive Freedom Amendment would add a new article to the state constitution's Declaration of Rights to guarantee the right to reproductive freedom, defined to include "the ability to make and effectuate decisions to prevent, continue, or end one's own pregnancy."

South Dakota

A ballot measure expanding abortion rights was also certified in South Dakota last month, where almost all abortions were banned after Roe v. Wade was overturned. The measure aims to prohibit the state from banning abortions in the first two trimesters. The ballot measure would allow the state to regulate a woman's abortion decision in a limited capacity during the second trimester: if the regulations are reasonably related to the physical health of the pregnant woman.

Proposed abortion-related ballot measures

Arizona, Arkansas, Montana, Nebraska and Nevada are still collecting signatures from voters in order to get measures on the ballot.

In Arizona, organizers say they will collect enough signatures in June to move forward with a ballot measure that would enshrine right to abortion in the state constitution.

In April, the Arizona House of Representatives overturned a state Supreme Court ruling that re-instated a near-total abortion ban from 1864.

Arkansas is working to get enough signatures for a ballot measure that would prohibit the state from banning abortions up to 20 weeks after gestation. If the measure is approved for the ballot and gets enough votes in November, it would allow for abortions in cases of rape, incest or to protect the life of the pregnant person.
