When was the last time that Washington saw the likes of Trump? Sarcasm aside, I like him because he's shaking up the establishment. And gosh darn it, isn't he supposed to be part of the establishment? An old, fat white guy is pissing off the other old, fat white guys.
He annoys the media. They needed shaking up.
He demonstrates the strength of the US political system. Left, right or centre, America stays the course. They are still the envy of the world.
I think that he is going to surprise people (in a good way) with NK and Russia. I'd love to be working the Intel script in SE Asia or E. Europe. Things aren't always as they appear.
He proves that Twitter isn't as influential as the snowflakes believe it is.
