Abortion will appear on 10 state ballots this November. Here's our guide to the reproductive rights measures.

Abortion has emerged as a key hot-button issue in the 2024 election — the first presidential election since the U.S. Supreme Court overturned the landmark Roe v. Wade decision that established a federal right to abortion with its 2022 Dobbs ruling.

Former President Donald Trump has boasted on the campaign trail that he was able to "kill Roe v. Wade" by appointing the justices that gave the court its current 6-3 conservative majority.

Vice President Kamala Harris says she would fight for safe, legal access to abortion if elected.

Over the past two years, abortion rights advocates have fiercely fought to reestablish reproductive freedom at the state level, either through legislation or citizen-led initiatives. So far, every one of those initiatives has prevailed for abortion rights advocates, even in red states like Kentucky and Kansas, where measures seeking to hinder abortion access have failed.

Come Nov. 5, abortion rights advocates are hoping to channel that momentum into support for even more ballot initiatives, which have proved to be a powerful guardrail against abortion bans.

Here’s where abortion will be on the ballot this election:
