Jay Feely leads the July 21, 2026, Republican primary for Arizona’s 1st Congressional District with strong trader support, reflecting his Trump endorsement, highest fundraising totals among declared candidates, and name recognition as a former NFL player and broadcaster. John Trobough trails as the next most viable option, drawing on his business background and prior White House service while emphasizing policy-focused messaging in recent debates. Joseph Chaplik, a former state representative, and lower-polling entrants such as Gina Swoboda and Paul Reevs face narrower paths amid a crowded field for the open seat previously held by David Schweikert. Recent May 2026 candidate forums and campaign finance reports have reinforced Feely’s positioning, though limited public polling leaves room for late shifts before ballots are cast.
