Arizona is a battleground state that both parties are desperate to win in November. And right now, supporters of abortion rights in the state are in the midst of gathering signatures to ensure that, along with the presidential race and a competitive Senate contest, enshrining the right to abortion in the state’s Constitution will be on the ballot this fall. The measure has broad support in the state, and Democrats are banking on that to drive a wide range of people to the polls to vote on the ballot measure — and, they hope, for Mr. Biden. But there’s no guarantee that will happen. For the next two weeks, we’re going to focus on how abortion rights could shape the 2024 election in Arizona. This week: We’re with volunteers around the state — at a trailhead outside Phoenix and at Bunco night in Bullhead City — who are working to get the measure on the ballot, and we spoke with the people who were supporting their efforts.
