Arizona's Democratic governor picked a longtime Republican-turned-independent as her lieutenant governor candidate, a cross-party gamble that reveals just how much trouble she knows she's in heading into November.
Gov. Katie Hobbs on Tuesday formally announced former Mesa Mayor John Giles as her running mate for the 2026 general election, rolling out the pick in a joint campaign video posted to social media. Giles, who spent more than a decade as the Republican mayor of Arizona's third-largest city, switched his party registration to independent on May 17 and voted in the Democratic primary weeks later, AP News reported.
The move is a frank admission of political gravity. Hobbs won her first term by a razor-thin margin roughly four years ago, leaning on moderate Republicans and independents to get across the finish line. She now faces Rep. Andy Biggs, a Trump-endorsed Republican who won his primary in a rout, and she is widely considered the most vulnerable Democratic governor in the country.
Picking a man who was registered Republican for decades is not a show of strength. It is a survival strategy.
Giles served as Mesa's mayor from 2014 to 2025. Mesa is no small suburb, it is Arizona's third-largest city, a reliably conservative community in the Phoenix metro area. For most of that tenure, Giles carried a Republican registration. But his drift leftward became impossible to ignore well before he formally changed his party affiliation.
In 2024, while still a registered Republican, Giles endorsed former Vice President Kamala Harris for president. He then traveled to Chicago and spoke at the Democratic National Convention, a stage that no Republican in good standing would share. Just The News reported that Giles dropped his Republican registration in May and voted in the Democratic primary the following month.
In the campaign video, Giles framed his party switch as a matter of pragmatism, not ideology:
"I was a lifelong Republican before becoming an independent because extremists shouldn't stand in the way of getting things done."
AP News quoted Giles more bluntly about his break with the party. "A few months ago, I realized that it was time to give up that crusade," he said, referring to what he described as an effort to save the Republican Party from within.
The pattern is familiar. Across the country, a small but visible cohort of officeholders and political figures have drifted between parties, or openly flirted with leaving their own. Sen. John Fetterman of Pennsylvania, for instance, has repeatedly tested the boundaries of his own party, though from the opposite direction.
What separates Giles from someone like Fetterman is the completeness of the journey. Fetterman quarrels with Democrats but stays. Giles endorsed the Democratic presidential nominee, spoke at the Democratic convention, voted in the Democratic primary, and now runs on a Democratic ticket, all within roughly two years. Calling him a "former Republican" is technically accurate. Functionally, he is a Democrat who has not yet updated his registration.
Hobbs pitched the pick as proof of her commitment to working across the aisle. In the campaign video, she said Arizona is making history with the new same-ticket format for governor and lieutenant governor, the first time the state has elected both offices on a single ballot, the Washington Examiner noted.
"The first thing I looked for in a running mate was someone who shares that value of putting Arizonans ahead of partisan politics."
Hobbs also claimed she has signed more than 900 pieces of bipartisan legislation into law during her tenure. That number is her campaign's figure; the source does not independently verify it or break down how many of those bills had meaningful Republican support versus routine, uncontested measures that pass every session.
More telling is what Hobbs chose to highlight alongside the bipartisan branding. She pointed to signing the repeal of Arizona's 1864 near-total abortion ban, a move that was, whatever one thinks of its merits, a top Democratic priority and a sharp partisan flashpoint. She also claimed credit for "cutting taxes" and "securing the border," though the announcement offered no specific legislation or data to back either claim.
When a reporter asked whether Democratic supporters might be frustrated by her choice of a former Republican running mate, Hobbs was dismissive. "It shouldn't be a surprise," she said.
She may be right that it shouldn't surprise anyone. The cross-party alliance is less a bold ideological statement than a cold electoral calculation. Hobbs barely won last time. Arizona remains a closely divided state. And her opponent this fall, Andy Biggs, carries President Trump's endorsement, a powerful asset in a Republican primary and a mobilizing force in a general election.
Giles is not the only political figure to cross party lines in recent cycles. The trend runs in both directions. Jill Biden's former press secretary endorsed a Republican candidate in Michigan's Senate race, a move that drew attention precisely because it broke with the tribal expectations of Washington's political class.
And Fetterman has not just questioned his party's direction, he has openly wondered whether Democrats have room for voices like his on issues such as Israel.
But there is a difference between internal dissent and a full defection. Fetterman stays and fights within his party. Giles left his party, endorsed the opposing presidential nominee, spoke at the opposing convention, voted in the opposing primary, and accepted a spot on the opposing ticket. That is not bipartisanship. That is a party switch with extra steps.
Hobbs's framing tries to have it both ways: she wants the credibility of a Republican name on her ticket and the policy freedom of a running mate who will never challenge her from the right. Giles, for his part, gets a path back to elected office without having to win a Republican primary he could no longer survive.
On the other side of the ballot, Rep. Andy Biggs heads into November with a straightforward pitch: he is the Republican in the race, endorsed by the sitting president. Biggs won his primary decisively, and he will face a Democratic incumbent who needs a former Republican on her ticket just to stay competitive.
Arizona's new same-ticket format for governor and lieutenant governor adds a wrinkle. Voters will choose the pair together for the first time, meaning Hobbs and Giles rise or fall as one. Hobbs described this as historic. Whether it helps or hurts her depends on whether voters see Giles as a genuine bridge to the center or as a political prop, a man who abandoned his party and now asks voters to trust his independence.
The open questions are significant. Hobbs's claims about cutting taxes and securing the border went unsupported by specifics in her announcement. Her "900 bipartisan bills" figure lacks independent verification. And the precise margin of her first victory, the number that defines just how vulnerable she really is, went unmentioned in the rollout.
None of that is accidental. A campaign that felt confident about its record would lead with numbers, not slogans.
When a governor has to recruit her opponent's former allies just to have a fighting chance, the bipartisan label is not a philosophy. It is a lifeline.
