Summary
Arizona posted 2026 House primary results with the sharpest focus on the 1st and 6th districts, two competitive seats likely to matter in the 2027 fight for House control.
In the open 5th District GOP race, Mark Lamb led Daniel Keenan 36,511 votes to 25,333—59.0% to 41.0%—after Rep. Andy Biggs left the deep-red seat to run for governor.
Other notable Democratic results included Amish Shah leading in the 1st District with 41.6%, Greg Stanton winning 66.6%, and Brandy Greene-Placentia taking 64.8%.
Several incumbents or uncontested candidates showed 0 votes in the posted tables, reflecting races without active primary competition rather than a broader statewide count.
The Arizona primaries offer an early map of where both parties will concentrate resources, with competitive suburban districts carrying the most national significance.
