Trump is a different animal altogether. He's the world's greatest living con man, and he's played a blinder with the red parts of the American public.
His bottom line is self-aggrandizement and his own pocket, and would literally say anything if those stumping up the cash were willing, or stupid enough, to pay his price. That's not to say that other American politicians are much better, but once you're in bed with Fat Anthony Salerno, the smell never leaves you.
