Jay Feely holds a commanding position in the Arizona 1st Congressional District Republican primary, scheduled for July 21, 2026, as traders assign him the highest probability among a crowded field of candidates seeking to replace the incumbent who is pursuing the governorship. Feely’s lead stems from his high name recognition as a former NFL player and broadcaster, substantial fundraising, and early alignment with President Trump, whose dual endorsements initially included other contenders before the race narrowed. Recent intra-party clashes, including Feely’s accusations against rival Joseph Chaplik over immigration-related comments, have kept the contest in the news without eroding Feely’s market dominance. Lower-probability candidates such as Chaplik and John Trobough remain active but trail significantly in trader assessments of primary momentum and voter support in the suburban Phoenix district.
