Mr Biden appears to be a decent human being who wants to improve things, by working a ludicrous system. Fair play, a high proportion of politicians start off that way, though many get cynical. Trump is in it out of an unbelievable sense of personal inadequacy, I'd reckon. He thinks that if he can get time-servers to grovel, he'll be happy, but he never will, I'm afraid, poor old bugger. A country so many of whose people are descended from those who failed at home and went there after easy money does encourage these fantasies about politicians, alas, but in fact they're a mixture, like everyone else, and the danger with them is not standard American greed but the urge to power. I'd have thought that was pretty obvious, frankly.
