For a third straight week, Democrats at the Arizona Legislature are attempting Wednesday to repeal the state’s near-total ban on abortions, again spotlighting an issue that has put Republicans on the defensive in a battleground state for the presidential election.

Republicans have used procedural votes to block earlier repeal efforts, each time drawing condemnation from Democratic President Joe Biden, who has made his support for abortion access central to his campaign for reelection.

Arizona Republicans have been under intense pressure from some conservatives in their base, who firmly support the abortion ban, even as it’s become a liability with swing voters who will decide crucial races including the presidency, the U.S. Senate and the GOP’s control of the Legislature.
