Trader consensus on Polymarket heavily favors the Republican nominee at 85% implied probability to win Arizona's 8th Congressional District House seat, reflecting the district's strong Republican lean with a Cook Partisan Voter Index of R+13 and consistent GOP margins exceeding 20 points in recent cycles, including Trump's 2020 victory by 24 points. Incumbent Rep. Debbie Lesko's retirement opened a competitive GOP primary, decisively won by Abe Hamadeh on August 6 with 52% of the vote, bolstered by endorsements from Lesko and national figures like Donald Trump. Democrat Iman Jalali advances unopposed but faces steep fundraising and polling deficits in this Phoenix suburbs stronghold. No major shifts post-primaries; upcoming general election ballot deadlines and early voting in October could influence late dynamics, though historical base rates signal low upset risk.
