You might see that, but I think it would only come after the fall of the party (if/when Trump or a post-impeachment successor would lose).  I do think the aftermath of Trump will likely eventually push for a radical re-evaluation by conservatives, but when?  Too many people seem to be emotionally invested.  A friend who is a Trumper likes the idea that he seems to step up and fight where others might have acquiesced.   Whether a fight is the best strategy or not seems to not matter to him.  But we'll see.  He's very much capable of introspection and thought.
