Democratic Arizona Gov. Katie Hobbs chooses former Republican Mayor John Giles as her running mate

PHOENIX (AP) — Democratic Arizona Gov. Katie Hobbs has picked a Republican-turned-independent to be her running mate in a tough reelection campaign, setting up a bipartisan ticket as voters elect the state's first lieutenant governor.

Hobbs' selection Tuesday of John Giles, a former mayor of Mesa, a Phoenix suburb that is Arizona’s third-largest city, is an overture to the Republicans and conservative independents she must win in a state that was once a GOP stronghold. Republicans have expanded their voter registration advantage over Democrats since Hobbs eked out a narrow win over Kari Lake , a fierce ally of President Donald Trump, in 2022.

Hobbs is considered the most vulnerable Democratic governor in the country. Giles, a registered Republican for decades, changed his party affiliation to independent on May 17 and voted in the Democratic primary last month, according to county voting records.

The Republican nominee is U.S. Rep. Andy Biggs , who last week picked Sine Kerr, a farmer and Republican former state lawmaker, to be his running mate. Kerr's rural roots balance Biggs' base in parts of metro Phoenix.

In an interview with The Associated Press before Hobbs publicly announced that she had picked Giles, he said he still considers himself to be a conservative and said he stuck around the Republican Party probably longer than he should have in a crusade to save it. "A few months ago, I realized that it was time to give up that crusade,” Giles said.

Giles, who was Mesa's mayor from 2014 to 2025, has been a vocal Trump critic and has endorsed Democrats, including Trump's 2024 rival, then-Vice President Kamala Harris. Giles spoke in favor of Harris at the Democratic National Convention, saying Trump's policies would hurt Mesa.

Giles also backed Democrats running against Trump allies , including Hobbs in her 2022 race against Lake and the state's current U.S. senators, Mark Kelly and Ruben Gallego.

As mayor, Giles signed a proclamation promoting equal treatment for lesbian, gay, bisexual and transgender residents in housing and accommodations, a controversial move in the conservative city.

The Biggs campaign, in anticipation of Hobbs' announcement, launched a website highlighting Giles’ support for Harris in 2024 and his participation in the Democratic convention.

As a member of the Church of Jesus Christ of Latter-day Saints, Giles can be an ambassador for Hobbs. Church members make up about 6% of the Arizona population. Latter-day Saints, widely known as Mormons, have been a reliably Republican voting bloc for decades, but many have been ambivalent about Trump since his first run for the White House.

Democrats have been working to woo Latter-day Saints turned off by Trump's penchant for foul language and demeaning rhetoric toward women and people of color, which clashes with the church’s values of humility, morality and compassion.

Biggs is also a member of the church.

Picking a Republican running mate hones the bipartisan image Hobbs has tried to create, contrasting with Biggs' background as a far-right congressman and, before that, the state Senate president. But it also risks inflaming tensions on the left.

In the AP interview, Hobbs said she takes a nonpartisan approach to her work in government. When she was asked whether some supporters might be frustrated because she picked a former Republican as her running mate, she said, “It shouldn't be a surprise.”

Both Hobbs and Giles portray Biggs as an extreme partisan. Giles said it’s disingenuous for Biggs to present himself as more of a moderate when he was “unapologetic about being the most conservative person in the room – in any room.”

Arizona is one of just five states without a lieutenant governor position, along with Maine, New Hampshire, Oregon and Wyoming.

That will change in January.

Voters added the post in 2022 to more clearly define the line of succession. Until then, the secretary of state will continue to serve as the next in line to be governor.

Gubernatorial succession is especially relevant in Arizona, where five governors since 1975 have entered the office through succession rather than election.

In fact, of Arizona's 12 governors over the past 50 years, only one, Republican Doug Ducey, entered and left the office through the typical pathways of being elected and serving out a full term. Among the others, one died, one was impeached and removed, one resigned after being convicted of fraud and two quit to accept presidential appointments.
