I don't think he's smart. But the Trump haters can't have it both ways: If he's NOT smart, then he sure as fuck didn't mastermind the Russian collusion thing.
But on the flip side I don't think he's much worse than any of the past 8-10 presidents we've had either. His biggest "fault" is his lack of decorum--his inability to let ANY comment go without a ridiculous tweet (well, that and a complete inability to remain on script when in front of a podium). Other than that I just don't see much difference...except he's actually gotten some things done (by being willing to say "fuck you" and working in very unconventional ways) on several fronts whereas his predecessors mostly just gave a lot of lip service:
* banking regulation reform
* tax reform
* North Korea problem
* Chinese trade deficit
* border wall
* Keystone pipeline
There are only a few things that bug me about him...
He crawled into bed with the deepest fringe of the sanctimonious relig-o-tards
people that would gladly bring this country to it's knees and cripple it for their true believer crap
See: Iran pre-revolution / post revolution
other than that he's exactly as he portrays himself
A hyper self absorbed Egomaniacal TV Personality that every criticism seems to hurt his feelings
who spends all his time blaming everybody else - zero accountability
He will be known as "the buck stops over there President"
He is exactly what this country deserves
and when it's all over nobody will have gotten what they want (nobody)
