More Old School Republican being wrong here. If overnight, a vast majority of sitting Republican officeholders decided to turn against Trump, then the base would go along with it, and decide that Trump was not a real Republican, while if only a few sitting Republican officeholders had decided to turn against Nixon back in 1973, then the base would have rallied around his defense. But the fact is that there is a major collective action problem that Republicans were able to deal with successfully in 1973, and that they have not attempted to deal with now.
I strongly disagree here
If every single Republican elected official turned on Trump, he would turn on them
Look at Flake and Corker. They retired because Trump had the power to primary them
