The open seat in Arizona’s 1st congressional district, vacated by longtime Republican incumbent David Schweikert’s gubernatorial bid, has drawn strong Democratic interest in the July 21 primaries. National party support, including a recent DCCC endorsement for former Republican Marlene Galán-Woods, positions Democrats to compete aggressively in this suburban Phoenix swing district with a slight Democratic lean. On the Republican side, former NFL player Jay Feely leads the primary field, yet traders assign the party lower odds amid broader midterm headwinds for the president’s party. The resulting market pricing reflects historical patterns in competitive open seats where turnout and candidate quality can shift narrow margins.
