@farmerman,
I think the chance of Trump getting past four years is about zero. But long before that four year period is done, the entire GOP/rightwing media machinery is going to have to shift the story it tells.
The obvious dilemma for them is how to do this. How do they reverse and move 180 from their heavily invested/proclaimed support for him to opposition while maintaining credibility to anyone who has a brain stem? Fox will be the key thing to watch.
Edit: What we do know is that everything they attempt will be supported by two techniques:
1) they will count on (for good historical reasons) the GOP base to easily swallow pretty much any rewrite of history they engage in - "Our long on-going battle with Oceania" even while a mere week ago it was Eastasia.
2) endless and broad repetition of the new message and brand
Actually there's a third
3) Hillary Clinton makes soup from aborted African American fetuses.
