McSally was a shyt Republican and the Trump backlash was intense.
Arizona, like Georgia is not a fan of Trumpism. Take the Trumpism back and run a normal Republican, things go back to the way they were.
I think Arizona has a lot of neocons, still. Some of those neocons jumped right on the Trump train, but not enough of them did.
There's lots of military settled there too because of Luke and Davis-Monthan. Those types loved John McCain and aren't fukking with someone like Kari Lake who doesn't like them right back.
You combine that with all the tech workers from CA who moved into Chandler, Tempe, etc., and Arizona is going to stay purple, especially because the Trumpists ran all the neocons out of the Arizona GOP and are running the show in Republican primaries. They're going to continue pissing off the neocons, who will stay home or vote for Dems who carry themselves like Mark Kelly.
Kelly is the perfect candidate to consistently carry that Senate seat. Astronaut, former military, carries himself like a moderate even though he votes with Biden regularly.
Gallego is a former Marine with charisma. That seat is his if not in 2024, in 2030. He's a great candidate.
