Overview
- Robson suspended her campaign on Feb. 12, saying a drawn-out, divisive primary would weaken Republicans heading into November.
- Her withdrawal leaves Reps. Andy Biggs and David Schweikert as the major GOP contenders for the July 21 primary, and she made no endorsement.
- Trump endorsed both Robson and Biggs earlier in the cycle; Biggs now remains the only Trump-backed candidate and also has Turning Point USA’s support.
- Pre-withdrawal polling showed Biggs with a wide primary lead, including an Emerson survey putting him at 50% to Robson’s 17%, with Schweikert at 8%.
- Post-exit signals show a modest Democratic boost, with Kalshi odds for Gov. Katie Hobbs rising to 66% even as Cook Political Report and Sabato still rate the race a toss-up for November 3.
