The sad truth is that there is only one way to avoid a death-match with the media and both parties on one side and Trump on the other. That way is to let the Mueller witch hunt play out. Afterward Trump can fire Sessions and Rosenstein on the same day—and I’d guess he will.
Btw, Nixon had something Trump doesn’t have: a semi-sane, somewhat rational electorate. Post-modernism has triumphed since then, and insanity is the order of the day. Sports Illustrated wouldn’t have put a mutilated male on its cover in Nixon’s day, and called it a woman. Today they do so with almost zero pushback—and that’s just one small example.
Could be. My estimation is, once Mueller releases his trumped up charges, there is more likelihood of defections of Republicans to Mueller's side. Some are waiting just for that, surely. When the Congressional (and possibly IG) reports are released, Trump will be at the high point of making his case to the public, and in the best position to make an offense/defense counter play. Hopefully that happens before Mueller arrests some more Trump team members, but it will probably be close. Also we should expect some sort of salacious media scandal to target Trump again soon too.
