Much of this doesn’t really make the AZ GOP any different from the national GOP or other swing state Republican state parties, but I agree that Lake shouldn’t get anywhere near the nomination for any statewide office. I still doubt that Mark Kelly will benefit this much from the AZ GOP's 'ideologically rightward/Trumpian/authoritarian' turn, though.
Obligatory reminder that this is the state that elected Jan Brewer by double digits in 2010, so I don’t think 'cringe' is exactly some groundbreaking, radically new development for the AZ GOP.
Jan Brewer was an establishment Republican who knew how to play to the base effectively. This is different, this is the inmates running the asylum at this point.
Considering Arizona is already voting Democratic now, it is rather clear that enough people have reached their tipping point regarding this madness and it just depends on whether "new majority" in AZ turns out or not.
