Arizona Governor Katie Hobbs, a Democrat, has secured her party's nomination for a second term after running unopposed in Tuesday's primary, setting up what is expected to be a closely watched contest in November. Arizona remains one of the most competitive battleground states in the country, and the outcome of the governor's race will be closely scrutinised as a bellwether for wider political trends heading into the midterms.

Hobbs, a former Arizona Secretary of State, narrowly won the governorship four years ago by defeating Republican nominee Kari Lake. With no Democratic rival this time, she moves directly to the general election campaign, where she is expected to face a competitive Republican challenger in a state that has swung between the two parties in recent election cycles.
