No they aren't and never have been. He started in John Rhodes old seat when Rhodes retired. He then picked up Goldwater's seat when he retired. In the outlying counties he gets Pinto Democrat votes but those almost always turn for the Republican in State or Federal offices.
I know how he started, I’ve lived here my whole life, that’s not how he’s stayed there, especially since he became a “maverick”. He would have been voted out long ago if it wasn’t for democrats.
