Bigworld, I think the Deep State figured that since they were stuck with Trump, they'd see if he could be useful to them, if not as the usual puppet then perhaps he could be coerced into pushing some agenda items - anti-Assad, anti-Russia, domestic austerity, de-regulate Wall St, etc.
But they may have decided to cut their losses and go with Pence, since even if Trump could be made willing, he's not able to deliver much due to his erratic personality and political ineptness.
Can't say I'm looking forward to a drawn out impeachment process though, considering how disheartening it was back in the Watergate years.
