Amish Shah holds an 86% implied probability in this open-seat Arizona 1st District race because forecasters including Cook, Sabato, and Inside Elections shifted ratings toward Lean Democratic after the July primaries, citing the district’s competitive profile and Shah’s edge in early October polling. The former state representative and emergency physician has emphasized bipartisanship, door-knocking outreach, and healthcare access while raising substantial funds and securing cross-aisle endorsements. Jay Feely, the Trump-endorsed former NFL kicker, trails at 14% amid the race’s focus on affordability, border policy, and data-center development; his primary win and debate defense of administration positions have not yet closed the gap in trader assessments ahead of November 3 voting.
