Trump may have more support than you know. I'm also reasonably sure, given what I've seen so far, that even though the folks who really need to see the inside of a cell may never do so, their ability to influence is being taken from bit by bit. Lying is almost their only weapon. Their loss of influence (add the media and Hollywood) will have a cumulative effect in the short run, I think.
Nah, that cabal has been building for 30 years at least. One man in office for one year isn't going to take them down. Besides, nobody in Washington DC wants to take them down. They want to take Trump down, and they probably will out of shear force of numbers. Trump is alone in Washington DC.
