He might be, I don't follow US politics closely (if there's a rumor he's about to die or he fucked some kids I'll read for a while, nothing happens though).
Anyway, as an outsider looking at this farce it seems they all were corrupt... All bought by the same interest groups no matter their political allegiance (which you have two, one more than dictatorships).
I think the worst was Obama, because people just love the guy, but he was George W in black face... A lot more intelligent, more charismatic and a way WAY better speaker, but it was the same guy, with the same politics. He wasn't worse than Trump, but Trump isn't liked by anyone anywhere (outside the US), Obama is.
