Unlike Goldwater or Reagan, Trump was never tied to Conservatism, Inc. He has been the most successful populist since Andrew Jackson. If Trump survives lawfare against him and election sabotage and becomes President, he will need to be as revolutionary as FDR. I was a little concerned that he had Lindsey Graham on the platform with him in South Carolina after his victory there. Graham is the epitome of a GOP establishment politician.
I don’t think that Reagan was Conservatism inc. Goldwater was a little too nuts on starting a nuclear war.
The John Birch Society was right about most things.
