This is why I don't see MAGA fading away - at least not by 2022.
McCain - Palin lost got their asses handed to them, then the Tea Party came roaring in in 2010. Then Romney loses and they have the infamous autopsy that says "hey, let's become more moderate, reach out to minorities." Then there's Trump and MAGA. 2018 happens and Trump doubles down on MAGA and gets 74 million votes.
The sensible Republicans will try to hold on, but still vote along party lines most of the time - i.e. Romney, Murkowski, Collins, Sasse - but I can't see Cruz, Hawley, Cotton, Blackburn, Johnson, Braun, Paul, etc. and the new House darlings like Boebert, Greene, and Cawthorn vanishing into the night.
