So what are the absolute odds that when (or if, don't want to get too cocky) Donald Trump wins... the DNC basically props up Joe Biden and who would be his picks for VP and Cabinet and try to set up a government in exile in like... Canada or France (or Germany)?
They wouldn't dare try. What you have to understand is that our politicians are not inventors, generals, businessmen, or poets. They don't get their power and wealth from talent, and few are charismatic without a network airbrushing them. AOC is really no different from any other TDS-infected twittee, and Pelosi is a day-drunk out-of-touch elitist with no real talent (think the mother from Arrested Development). They get their power from connections.
It's why when Hillary lost, the suits who'd groomed themselves into the aristocratic bureaucracy went nuts: it was a domino effect of connections meaning nothing. Her campaign staffers literally had "I'm with her" as the best they could come up with, after millions of dollars and years to plan. How inspirational: a phrase you say to the salesgirl when your wife drags you shoe shopping. If Hillary had won, those connections would have insured they got some cushy position they were in no way qualified to in her administration. Now, those connections are useless, and they have no real talent to fall back on. Trump crashing the election is to them what a stock market crash is to a retiree's 401K: the sum of their labors, gone. (This is also some of the never trumpers as well: Trump was a shock to the inbred, nepotistic spider's web as a whole. He is as much a threat to the Romneys as he is the Kennedys).
If they try a stunt like that, they essentially lose all the connections, because red tape and favors only go so far, and never under much heat. If Pelosi tried to become De Gaulle, she'd be leading an army of her hanger-ons and brown nosers. I hope the bootcamp has gluten-free options. Trump would declare her a traitor, sieze her vineyards and whatever other assets she had to abandon, and let her FOAD like Iran is letting the crown Shah in Miami or the Dalai Lama with China. She brings nothing to the table without her web.
The other question: where would she go? Europeans might be uppity, but they're like spoiled teenagers: when Daddy America puts his foot down, they know to keep their heads down and only say "Yes sir". China might, but living in the Sino-shithole is a punishment no matter how rich you are, and you're just waiting for the next bowl of undercooked bat soup to come along. Africa loves coups, but I don't see Pelosi matching General Buck Naked in flair. Russia has no love for longtime American government officials, and Putin wouldn't find it worth the work to thumb his nose at us for any of them. Most latin countries want good trade with America without American globo-homo; La Résistance gives them the worst in both directions. And if you delve into conspiracies, she can't even join your average A&H poster under Antarctica because she a cryptojevv.
