U.S. Representative Andy Biggs won the Republican nomination for Arizona governor in the July 21, 2026, primary, defeating three GOP opponents including U.S. Representative David Schweikert, who had been regarded as the more pragmatic, moderate contender in the field. Biggs, endorsed by Donald Trump, will face Democratic incumbent Governor Katie Hobbs in the November 3 general election.

Biggs refused to certify the 2020 presidential election results, citing Trump's unverified claims that the election was stolen. In the 2022 governor's race, Hobbs narrowly defeated Republican Kari Lake. Trump won Arizona in the 2024 presidential election, keeping the state in swing-state territory — meaning neither party has a reliable lock on it.

The Cook Political Report, a nonpartisan group that rates the competitiveness of political races, had labeled the governor's race a toss-up ahead of the primary. After the results, Cook shifted its rating to a slight Democratic advantage.

Trump's influence extended to other races on the ballot. Alexander Kolodin won the Republican nomination for secretary of state, the office that oversees elections in Arizona. Kolodin, an attorney, participated in lawsuits challenging the 2020 election results. Adrian Fontes, a Democrat, currently holds the office.

In Arizona's 1st Congressional District, former NFL kicker Jay Feely, endorsed by Trump, won the Republican nomination over Joseph Chaplik, a hardline former state lawmaker who was a member of the Arizona legislature's Freedom Caucus, a group of conservative legislators.

The primary drew national attention for what it revealed about voters in a key swing state. Two of the 18 congressional districts rated as true toss-ups nationally are in Arizona. Reuters reported on July 21 that Democrats were banking on Republicans nominating far-right candidates in Arizona, calculating that such nominees would be less competitive in the general election.

The NPR report on the results, published July 22, included an Associated Press photograph by Ross D. Franklin showing a poll worker assisting an Arizona voter at a Phoenix polling location. PBS NewsHour carried live results coverage of the Arizona midterm primaries.

The general election is scheduled for November 3, 2026, with early voting beginning October 7. Maricopa and Pima Counties must mail sample ballots at least eleven days before a general election. The Arizona Secretary of State's office maintains an unofficial election night results page, and full results are available through the state's election information portal.

The broader context here is that Arizona Republicans have now nominated candidates for two of the state's top three offices — governor and secretary of state — who both challenged or objected to the 2020 election results. In a state Trump carried in 2024 by a margin narrow enough to keep it competitive, the question for November is whether the party's primary voters have selected nominees who can win enough centrist votes to prevail statewide, or whether the Democratic strategy of facing ideologically uncompromising opponents will hold. The Cook Political Report's post-primary shift toward Democrats suggests at least one nonpartisan handicapper sees an opening for Hobbs. But Trump's 2024 Arizona win and the state's toss-up House districts indicate the partisan baseline remains close enough that candidate quality and turnout will likely decide the outcome.
