Arizona's 5th congressional district carries an R+10 Cook Partisan Voting Index and delivered a 20-point margin for the Republican presidential nominee in 2024, establishing a durable structural advantage for the GOP nominee. The July 21, 2026 primaries produced clear winners—former Pinal County Sheriff Mark Lamb on the Republican side with a Trump endorsement and Elizabeth Lee on the Democratic side—setting up a general-election matchup on November 3. With the seat open after incumbent Andy Biggs pursued a gubernatorial bid, traders have priced in the district's consistent Republican performance and limited crossover appeal, resulting in the 87.5% Republican consensus. No subsequent polling or events have altered the partisan baseline.
