Developments this week in Arizona underscored something that was already apparent about the 2024 elections in the United States: Abortion is going to loom large as an issue in state and federal elections — including the presidential race — and directly in the form of referendums in some states.

An Arizona Supreme Court ruling that allows enforcement of a ban on abortion at all stages of pregnancy was part of a flurry of recent activity on the issue that has been in flux since the U.S. Supreme Court overturned Roe v. Wade and undid a national right to abortion in 2022.

At the moment, 14 states are enforcing bans on abortion at all stages of pregnancy, and two have them currently in place after about six weeks of pregnancy, before many women realize they are pregnant. Both numbers will rise within weeks because of recent court rulings, barring any surprise legislative or court action.
