Hobbs Picked a Running Mate Who Already Left the Party

Gov. Katie Hobbs reportedly wants former Mesa mayor John Giles as her lieutenant governor, and the pitch is already familiar: a Republican on a Democratic ticket, a bridge to the center, Arizona over party. There is one small problem with the framing. Giles is not a Republican anymore.

Maricopa County voter records obtained by KTAR show Giles changed his registration from Republican to no party preference on May 17, three months before the New York Times reported Hobbs planned to name him to the ticket. He had been a registered Republican since at least 1986. In the July primary, his file listed him as other, and he requested a Democratic ballot. The bipartisan headline is built on a man who quietly filed the paperwork to stop being one.

This is not a gotcha about dates. It is the whole story. The Hobbs Arizona Over Party coalition needs a Republican willing to cross over. Giles has been doing the crossing for years. He endorsed Sen. Mark Kelly in 2022, backed Hobbs for governor that year, co-chaired Republicans for Harris in Arizona in 2024, and spoke at the Democratic National Convention in Chicago. Maricopa County Republican committees and several Mesa-area legislative districts censured him for it. By the time he reregistered, the only people surprised were people not paying attention.

So who is the gambit for? Not the Republican base. Trump-aligned voters do not see Giles as a bridge. They see a defector, and they have the censure votes to prove it. The voters most likely to be moved by a Republican for Hobbs pitch are the voters already moving. Center-right suburbanites who flinched at Andy Biggs can be reassured by Giles. The voters who like Biggs were never going to be reassured by a man who campaigned for Kamala Harris.

That is the backfire risk, and it runs both directions. On the right, Giles gives Biggs a decade of Mesa headlines and a registration change to wave at. On the left, he hands a real office with real authority to a former Republican while Arizona Democrats are asked to cheer. The lieutenant governor is first in line of succession and holds an appointed post under the governor. Some progressives will ask why a Democrat was passed over for a man who voted a Republican ballot as recently as July 2024. A few may decide the ticket is not worth the trip.

The contrast with Biggs's pick, former state Sen. Sine Kerr, sharpens the problem. Kerr reinforces the Republican coalition: rural ties, dairy-country credibility, ideological consistency. She does not pretend to be something she is not. Giles's value depends on voters not checking the date on his registration form.

There is a serious version of the Hobbs argument. The new No. 2 job is a governing position, and Giles ran a big city for a decade. Mesa added people, rebuilt downtown, and landed an ASU campus on his watch. The Arizona Globe's own opinion writer concedes the city's 2024 crime rates were low for its size. That is a real record.

But competence arguments require trust, and trust requires honesty about who is being hired. A campaign that calls Giles a Republican bridge is asking voters to admire a coat of paint the candidate himself took off in May. The more honest pitch is that Hobbs wants a former Republican who already agrees with her, and she hopes the label still sticks in the public mind after the registration lapsed.

Arizona voters can handle that argument. They split tickets, punish incompetence, and reward adults. What they tend not to reward is being flattered by a label the candidate no longer carries. Hobbs won narrowly in 2022 against a damaged opponent. She is not entitled to a second look, and she is not entitled to one built on a registration change her own running mate arranged in private.

The Giles gamble could still work if the race turns on temperament and Biggs overplays his hand. But the upside is narrow: hold the Republicans you were already going to lose by less, and hope the Democrats you annoyed stay home rather than walk. That is a comfort, not a coalition.
