This makes me think that a not-entirely-crazy scenario is a 270-268 Trump win (with NC, Florida, Nevada, NH & 1 from Maine), followed by some new Trump revelation, resulting in a couple of faithless electors going for, say, Paul Ryan or Mitt Romney, before it's thrown to the House who undertake a coup in the name of compromise/wound-healing. That seems the type of fan-fic that, this year, is semi-plausible. The key is for something 'disqualifying' to occur post-election, upon which some justification (however unconvincing) could be grounded.
I don't think this is possible. Cause the degree of polarization AND outright contempt of voters for outside intervention would make this a nightmare choice, and won't secure a more stable outcome.
Anyway, it is even tiresome for me to look at this election, and i am not even voting or living in the US... Difficult times.
