Arizona’s 5th congressional district, covering East Valley suburbs in Maricopa and Pinal counties, carries a Cook Partisan Voting Index of R+10 and has delivered consistent double-digit Republican margins in recent cycles. The seat opened when incumbent Andy Biggs sought the governorship, leading to a July 2026 Republican primary won by former Pinal County Sheriff Mark Lamb, who secured the nomination with Trump endorsement and roughly 59 percent of the vote. Democrat Elizabeth Lee emerged from her primary to face him in the November 3 general election. Nonpartisan ratings classify the race as Solid or Safe Republican, aligning with trader consensus that prices Republican victory near 90 percent while assigning the Democratic nominee single-digit implied probability based on the district’s voting history and structural advantages for the GOP nominee.
