The biggest and messiest races in Arizona’s 2026 primary election

Arizona voters participated in the July 21, 2026, primary election to select Republican nominees for key statewide offices, including governor, secretary of state, and attorney general. According to election officials, the outcomes will determine the GOP challengers facing incumbent Democrats such as Gov. Katie Hobbs and Secretary of State Adrian Fontes in the November general election.

The Republican primary for governor remains one of the highest-profile contests in Arizona’s 2026 election cycle, with U.S. Reps. Andy Biggs and David Schweikert, along with businessmen Ken Miceli and Scott Neely, vying for the nomination, according to reports from ABC15 and local media. The winner will face incumbent Democratic Gov. Katie Hobbs in the November general election, officials said. Phoenix New Times noted the gubernatorial race as a key contest, highlighting the possibility of Hobbs facing either Biggs or Karrin Taylor Robson in November.

Early voting for the primary began June 24, 2026, with the election held July 21.

The secretary of state race is another significant statewide GOP primary. State Rep. Alex Kolodin and former Arizona Republican Party chair Gina Swoboda are among the candidates competing for the nomination, according to local coverage and ABC15. The Republican nominee will challenge incumbent Democratic Secretary of State Adrian Fontes in the general election. FOX 10 Phoenix listed secretary of state as one of the major statewide offices on the ballot for the July 21 primary.

The attorney general primary is described as particularly contentious. Axios reported that the Republican contest features Rodney Glassman and Senate President Warren Petersen as leading candidates. The winner will face Democratic Attorney General Kris Mayes in November. Phoenix New Times included attorney general among the key races to watch in 2026, while ABC15 and FOX 10 Phoenix confirmed it as part of the statewide primary election.

In the race for superintendent of public instruction, Republican incumbent Tom Horne is challenged by State Treasurer Kimberly Yee, according to AZ Luminaria and Axios voter guides. FOX 10 Phoenix also identified this office among the statewide positions on the primary ballot. The victor will advance to the general election in November.

The treasurer’s race features Republicans Katherine Haley and Elijah Norton competing for the GOP nomination, with Nick Mansour running as the sole Democrat, Axios reported. FOX 10 Phoenix included treasurer on its list of statewide offices for the 2026 primary. Voters will select nominees on July 21 ahead of the general election.

The Arizona Corporation Commission race includes state Rep. Ralph Heap, a member of the Arizona Freedom Caucus, running against incumbents Nick Myers and Kevin Thompson, according to Axios. The report noted that David Marshall resigned from the House to become Navajo County recorder, creating a vacancy related to the commission race. FOX 10 Phoenix also listed Corporation Commission among the statewide offices on the primary ballot.

On the congressional front, Arizona’s 1st Congressional District is described by Axios as the most hotly contested congressional race, with three Republicans and five Democrats competing in crowded primaries. The seat is open because longtime incumbent David Schweikert is running for governor, sources confirmed. The 5th Congressional District is another open-seat race, with Republicans Daniel Keenan and former Pinal County Sheriff Mark Lamb facing off in the primary, Axios reported.

All 90 seats in the Arizona Legislature are up for election in 2026. Republicans hold narrow majorities in both chambers entering the cycle, according to state records.

Arizona’s primary election was moved to July 21, 2026, from the traditional August date after state lawmakers shifted it to the second-to-last Tuesday in July, ABC15 and FOX 10 Phoenix reported. Early voting began June 24. Ballots could be mailed by July 14 or returned at official drop boxes, early voting locations, or vote centers by 7 p.m. on Election Day, according to Axios. ABC15 noted the earlier schedule was adopted to allow election officials sufficient time to meet federal deadlines in case recounts are necessary. The general election is scheduled for November 3, 2026.
