Trump's endorsement has positioned Jay Feely as the clear frontrunner in the July 21 Republican primary for Arizona's 1st Congressional District, reflected in the 78% market consensus. Feely's substantial fundraising edge and background as a former NFL player and broadcaster have consolidated support in this open seat race. Recent Axios reporting on Joseph Chaplik's May social media comments criticizing Feely's assistance to Haitian immigrants intensified intraparty tensions and highlighted immigration divides, contributing to Chaplik's trailing 19% odds. Chaplik's resignation from the state House to focus on the campaign and his prior attendance record have drawn scrutiny from rivals. The remaining candidates trail far behind with minimal visibility or resources, leaving little room for shifts absent major late developments before primary day.
