Key takeaways

  • Arizona Governor Katie Hobbs has selected former Republican Mayor John Giles as her running mate for re-election.
  • Giles recently changed his party affiliation from Republican to independent and voted in the Democratic primary.
  • The selection aims to attract Republican and independent voters in a competitive gubernatorial race.

What Happened

Democratic Arizona Governor Katie Hobbs announced Tuesday that she has chosen John Giles, the former Republican mayor of Mesa, to be her running mate for her re-election campaign. This selection creates a bipartisan ticket for the election of Arizona's first lieutenant governor.

Giles, who was a registered Republican for decades, changed his party affiliation to independent on May 17 and voted in the Democratic primary in the month prior, according to county voting records. He served as the mayor of Mesa, Arizona's third-largest city, from 2014 to 2025.

Why It Matters

Hobbs, considered one of the most vulnerable Democratic governors nationally, faces a competitive race in Arizona, a state that has seen an increase in Republican voter registration since her narrow 2022 victory. Giles's bipartisan appeal is seen as an effort to win over Republican and conservative independent voters necessary for her re-election.

The Republican nominee, U.S. Rep. Andy Biggs, has selected former state lawmaker Sine Kerr as his running mate. The Biggs campaign has highlighted Giles' past support for Democrats, including endorsing Kamala Harris and speaking at the Democratic National Convention, framing him as aligned with Hobbs on issues they claim have harmed Arizona.

Background

Voters will elect a lieutenant governor for the first time this fall following the approval of a ballot measure in the 2022 election. Hobbs previously served as Arizona's secretary of state and held leadership positions in the state Senate and House.

Giles has been a vocal critic of Donald Trump and has endorsed Democratic candidates, including Kamala Harris and Senators Mark Kelly and Ruben Gallego. As mayor, he signed a proclamation promoting equal treatment for LGBTQ+ residents. Giles stated he left the Republican Party because "extremists shouldn’t stand in the way of getting things done" and that the party had been "kidnapped by extremists."
