Masters' campaign just seems like a total mismatch for the state he's in. Arizona is not a very socially conservative state (even Goldwater was pro-choice) and I really don't think swing voters in Maricopa want to hear any more BS about "audits" and how akshually Trump won.
Brnovich isn't necessarily a lock either, but he'd be a much better bet as long as he doesn't bend too far towards the Gosar types in the primary.
From the ads I’ve seen of masters he seems pretty elequent and soft spoken. Not like Trump at all. Also unlike Trump he isn’t talking sh**t on McCain and has a much friendlier environment
