Arizona's 5th congressional district maintains a consistent Republican lean reflected in its partisan voting index and voting patterns across recent cycles, which underpins the strong trader consensus favoring the Republican nominee. Incumbent Andy Biggs retired to pursue the governorship, leaving an open seat where former Pinal County Sheriff Mark Lamb secured the GOP nomination in the July 21 primaries and faces Democratic nominee Elizabeth Lee in the November 3 general election. Forecasters rate the race as solid or safe Republican. Factors that could still shift outcomes include late-cycle national political shifts, candidate-specific developments, or unusually high Democratic turnout in the East Valley suburbs.
