President Donald Trump's influence over the Republican Party continues to shape primary contests across the nation. Arizona's Tuesday primary offers a fresh test of his clout as he backs several candidates in races that could affect control of the House and governorships.
Trump’s endorsements in Arizona target the GOP gubernatorial nomination, the attorney general contest, and two congressional districts. His support can sway tight primaries and set the stage for the November general election.
In the gubernatorial race, Trump backs former Freedom Caucus chair Andy Biggs, who faces Rep. David Schweikert and others. Biggs, also endorsed by Turning Point USA, is viewed as the frontrunner, while the winner will challenge Democratic Gov. Katie Hobbs.
The attorney general primary has become heated, with Senate President Warren Petersen clashing with military attorney Rodney Glassman. The victor will face Democratic incumbent Kris Mayes in the general election.
For Arizona's 1st Congressional District, Trump endorses former NFL player Jay Feely. The Democratic primary pits former anchor Marlene Galán-Woods against physician Amish Shah, with Shah emerging victorious in the 2024 contest.
In the 5th District, Trump supports former Pinal County Sheriff Mark Lamb against contractor Daniel Keenan. Keenan has raised allegations of misconduct, though an investigation cleared Lamb of wrongdoing, and Trump reaffirmed his endorsement.
These contests are pivotal for the GOP's slim House majority and control of state offices. A Republican win in Arizona's 1st District could reinforce the party's hold on the House, while losses would widen the margin.
Trump’s endorsement record includes victories in Indiana, Kentucky, Texas, Georgia, Alabama, and South Carolina, but recent defeats in Iowa, Louisiana, and New York show limits to his influence. His support for Rep. Randy Feenstra in Iowa failed to secure a win, and his backing of Rep. Julia Letlow in Louisiana ended with a victory, yet the pattern of mixed outcomes persists.
The Arizona primary illustrates both the reach and the constraints of Trump’s endorsement power. As the GOP navigates these contests, the outcomes will signal how much weight his backing still carries in shaping the party’s future.
