Former Pinal County Sheriff Mark Lamb commands 95.8% trader consensus in the AZ-05 Republican primary due to President Trump's November 2025 endorsement— a pivotal force in Arizona GOP contests—coupled with his strong December 2025 polling lead among likely primary voters and name recognition from his prior U.S. Senate bid. The open seat vacated by Rep. Andy Biggs for a gubernatorial run has seen a fragmented field, with State Rep. Travis Grantham at 2.5% and former NFL player Jay Feely at 0.3% after switching districts in January 2026; petitions certified in March left no late entrants. Recent skips by Lamb at a May 7 debate and forum amid Daniel Keenan's fundraising edge (three times Lamb's cash) have not dented odds, reflecting trader confidence in Lamb's base consolidation ahead of the July 21 primary. Upsets could stem from scandals, a challenger endorsement surge, or depressed turnout, though historical GOP primary patterns favor early frontrunners.
