Jay Feely holds a strong lead in the July 21, 2026, Republican primary for Arizona’s 1st Congressional District, reflecting trader consensus on his advantages in fundraising, name recognition, and high-profile endorsement. As the open seat race to succeed Rep. David Schweikert intensifies, Feely’s campaign has raised substantially more than rivals and secured early support from former President Trump. State Rep. Joseph Chaplik, who resigned his legislative seat to focus on the contest, trails amid reports of lower fundraising totals and negative exchanges with Feely over past associations and policy differences. Lesser-known candidates including John Trobough and others register minimal market interest. Key upcoming factors include voter outreach in the Scottsdale-centered district and any additional endorsements before primary day.
