President Donald Trump's influence over the Republican Party was on display in Arizona's primary elections, as his endorsed candidates won key contests across the ballot while Democrats avoided nominating a far-left candidate in a competitive House race. The results are being framed as a test of Trump's continued sway over GOP voters ahead of the November midterms, with implications for several high-profile races including the state's governorship.

Among the notable results, Rep. Andy Biggs won the Republican gubernatorial primary, setting up a general election matchup against Democratic incumbent Katie Hobbs, who was renominated by her party. A Trump-backed former NFL player and an ex-sheriff also won their respective primaries, while a vulnerable Republican incumbent held on in a competitive district. On the Democratic side, a moderate candidate fended off a progressive challenge in a Sun Belt battleground race, denying the party's left flank an upset heading into the autumn campaign.
