I don’t think that actually jives with electoral history of Arizona…where you can’t spell CRAZY without R-AZ.
Jeff Flake, for example, was hardly a moderate republican. He ran as an extreme tea bagger, and that’s how he won. McCain had time on his side, but his past few campaigns were against extremist republicans. Their history of governors has not had any I would call “moderate” in at least the past 10, probably closer to 20 years. And lets not forget Arapario who is running for Sheriff again…after toying with running against McSally in a primary.
