Jay Feely holds a commanding lead in the AZ-01 Republican primary market due to high-profile endorsements from President Trump and House GOP leadership, including Speaker Mike Johnson and other top officials, combined with strong name recognition from his NFL career and superior fundraising. Joseph Chaplik, a former state representative who resigned his seat to campaign, drew earlier polling support from conservative factions but has faced attacks over past statements and mudslinging that appears to have eroded momentum in the crowded field. The July 21 primary remains weeks away, leaving limited room for late shifts, while lower-polling candidates like John Trobough and others show no signs of consolidating support. Trader pricing reflects these endorsement and visibility advantages in a toss-up district primary.
