I have never seen anybody so determined (since the Bushies and Romney folks) to foist such a no traction candidate as Martha McSally on Arizona over and over again.
I worked in many parts of the US over the years, including California & Colorado. One thing I noticed as the Republican Party in those two States was sliding into irrelevancy: GOP politicians & insiders seemed more interested in criticizing other Republicans, than they did in defeating the Dems & electing our own candidates. When I moved to Arizona, I saw exactly the same behavior, including non-stop public griping about McSally, right up to election day. Hate to say it, but looks to me like Arizona is headed the same direction as California & Calirado (which is one reason I left).
