Thinking: If Donnie resigns,

[Warpy]

2. I think that is one huge "IF."

While I don't see him completing four years, I don't think things have gotten hot enough for him to resign any time soon. He still has his keepers in the White House with him, although he does miss Flynn. Pick off a few more of those and make him more isolated, surrounded by functionaries whose job it is to limit the damage he's doing, he'll finally get frustrated enough to blow a fit and quit. Or make it hot enough that he's facing what Nixon did, an imminent impeachment that would likely result in his removal and prison he will try to cut a deal to leave quietly in exchange for his pension.
