I saw Mitt Romney in an interview a few weeks ago saying we likely will see Trump style politics being used by some Republican politicians for a while. He felt there will be Republicans who still feel it’s a way to win. The way I interpreted it was he was saying just that, a way to win, not necessarily that the politicians felt it was good or right.
I think in two years we will see if it wins local offices and that will help decide if Republicans still market themselves that way.
I just read this article about QAnon, let’s see if that falls apart. That might have some influence. https://www.washingtonpost.com/technology/2021/01/20/qanon-trump-era-ends/
