Hard-right congressman Andy Biggs, endorsed by Donald Trump, has won the Republican primary for governor of Arizona, setting up a November showdown with incumbent Democratic Governor Katie Hobbs. Biggs, a former chair of the House Freedom Caucus who played a central role in efforts to overturn Trump's 2020 election defeat in Arizona, defeated fellow congressman David Schweikert, who had argued that Biggs' uncompromising politics would cost Republicans in the general election. The race is considered one of the most consequential in the country — Arizona (a key southwestern swing state that became a flashpoint for election disputes after Trump's narrow 2020 loss there) has shifted dramatically toward Democrats over the past decade, and control of the governorship carries significant national implications heading into the 2026 midterms.
