Arizona’s East Valley has an open congressional seat, a shifting political map and a quietly high-stakes race already taking shape for 2026. With Rep. Andy Biggs running for governor, a crowded primary field has moved in, and early snapshots suggest Republicans hold a built-in edge, but the real fight will be over who can lock down the local vote once summer hits.
What the New York Times snapshot shows
A polling tracker from the New York Times, updated May 11, offers an early read on Arizona’s 5th District, following both the primary maneuvering and hypothetical general-election matchups. In those early head-to-head tests, the Times currently shows Republicans out in front, even as the GOP primary itself remains wide open.
Why Republicans start with the edge
The Cook Political Report pegs AZ-05 as R+10 and rates the open seat as a solid Republican hold, underscoring how steep the climb looks for Democrats. That partisan baseline, Cook notes, is grounded in past election results and the district’s voting habits.
The seat came open after Rep. Andy Biggs launched a bid for governor, a move that scrambled East Valley politics. Axios reported Biggs’s gubernatorial plans back in January, effectively greenlighting every ambitious Republican in the district.
GOP primary: Lamb, Keenan and a crowded field
Former Pinal County Sheriff Mark Lamb is getting early “favorite” chatter from local outlets, thanks to his high name recognition and long-running profile in county law enforcement. Arizona’s Family highlighted Lamb’s late-2025 entry into the race and the expectation that his law-and-order résumé will resonate with Republican primary voters.
But this is no coronation. Gilbert contractor Daniel Keenan has been pointing to his fundraising and internal polling, according to the Daniel Keenan campaign, while former NFL kicker Jay Feely jumped in this April. Coverage from Roll Call suggests this primary could come down to organization, key endorsements and which contender manages to unify the pro-Trump and law-and-order factions inside the GOP.
Democrats: testing the waters
On the Democratic side, nurse and veteran Brian Hualde, nonprofit CEO Chris James and nurse Elizabeth Lee have either filed or launched campaigns, even as party officials acknowledge the November path is narrow in a Republican-leaning district. The Brian Hualde campaign leans heavily on health care and veterans’ issues, while ICT reports that James is centering outreach to Native communities as part of his pitch.
What to watch next
Arizona’s primary is scheduled for July 21, 2026, according to the state’s official election calendar, leaving a tight window for gathering signatures, raising cash and hitting the pavement before ballots are locked in. The Arizona Secretary of State’s calendar lays out that compressed timeline, which means fresh independent polling, high-profile endorsements and a likely rush of out-of-state money should arrive sooner rather than later as candidates scramble to break out before the summer vote.
