Republican grifters work best when Republicans don't have all the power. They can blame all your issues on the libs and the communists and support people who will never win like Ron Paul and rake in millions. When they are in charge, the people they have to blame gets silly. Deep state, Jewish cabal of Globalists etc works for a short while, but then all the changes they said will make everything better go into place and things get even worse.
Even worse for them is those who straddled the line to be able to market to whoever was in charge (the Phil's, Harveys, Ozes etc) decide to either join the "strong" or just finally stop faking who they were in the first place and find themselves in an oversaturated sea of people pulling the same grift. With ever poorer marks.
