Former Pinal County Sheriff Mark Lamb commands 95% trader consensus in the AZ-05 Republican primary due to President Trump's November 2025 endorsement, dominant internal polling showing him leading by 47 points or more, and state Rep. Travis Grantham's March 2026 withdrawal for Air National Guard active duty, clearing a key rival from the open seat race vacated by Rep. Andy Biggs. Lamb's strong name recognition, fundraising edge, and conservative credentials in this safely Republican East Valley district solidify his frontrunner status ahead of the July 21 primary. Challengers like former NFL kicker Jay Feely trail far behind, but late scandals, a damaging debate performance, or unexpected entrant could narrow the gap in the final stretch.
