Trump-backed Republican Karrin Taylor Robson dropped her bid for Arizona governor Thursday, setting up Rep. Andy Biggs (R-AZ) as the only Trump-endorsed candidate in the now two-person GOP primary.
Trump made the rare decision in April 2025 to back both Robson and Biggs in the 2026 Arizona gubernatorial race. The GOP primary to choose who takes on Gov. Katie Hobbs (D-AZ) in the general election grew to three candidates in November 2025, when Rep. David Schweikert (R-AZ) hopped into the race. Robson said she’s bowing out to avoid a divisive primary.
“We cannot afford a divisive Republican primary that drains resources and turns into months of intraparty attacks,” Robson said in a statement. “It only weakens our conservative cause and gives the left exactly what they want: a fractured Republican Party heading into November. With so much on the line in 2026, I am not willing to contribute to that outcome.”
The latest Emerson College poll had Biggs leading Robson by 33 percentage points in the primary challenge, estimating Biggs at 50%, Robson at 17%, and Schweikert trailing at 8%, with 25% of voters still undecided. As the two Trump-backed candidates, many of Robson’s voters are likely to swing toward Biggs.
Biggs also boasts the endorsement of Turning Point USA.
Robson, a former Board of Regents member, did not endorse another candidate in her immediate statement. Robson ran in the 2022 GOP primary, losing to Kari Lake by about 4.9 percentage points.
