Arizona’s 4th Congressional District race in 2026 appears to include Greg Stanton and Kai Newkirk , with Stanton listed as the incumbent seeking reelection and Newkirk also filed for CD4. A separate source also describes the district as an open-seat flip opportunity and mentions Zuhdi Jasser as a Republican candidate, but that conflicts with other 2026 CD4 listings, so the safest current read is that Stanton and Newkirk are the clearly confirmed names from the available results.

What’s confirmed

  • Greg Stanton — candidate for reelection to U.S. Congress CD4.
  • Kai Newkirk — candidate for election to U.S. Congress CD4.
  • Arizona’s House filing deadline has passed, and the state is holding U.S. House primaries on July 21, 2026.

Important note

The race can still shift if there are late ballot-access disputes, write-ins, or endorsements that don’t show up in the same public listings. One source also references Zuhdi Jasser in CD4, but it does not align cleanly with the candidate lists that explicitly name CD4 contenders, so I would treat that mention cautiously until the official candidate list is checked.

Election timing

  • Primary: July 21, 2026.
  • General election: November 3, 2026.

Would you like me to turn this into a cleaner candidate list with party labels and the latest district-4 status?
