That's a pretty strong accusation, and one he doesn't really present sufficient evidence to support here. He claims a "government-in-exile" situation without explaining who that benefits (who's in charge of the government-in-exile? Certainly not Clinton. Apparently not the Democratic party).
In essence, he appears to be buying into an illuminati-grade conspiracy that "they" don't want a Trump Presidency without a lot of support for why or how the alternative benefits them, which is irresponsible and sad coming from Taibbi. Especially since the simpler explanation - the guy with a history of corruption has done something corrupt - is at least as plausible and would necessitate the intelligence community to respond in some way (while still doing their damnedest to maintain their oaths of office in light of the Commander-in-Chief being someone they know is a crook).
