Under normal (whatever that is these days) circumstances, I would be reasonably confident that a person like Trump would lose a general election.
However, with the mass of (mindless) fans this guy has, including those who are adamant they would/will vote for him even if he is convicted of a criminal offence, further bolstered by all those selfish, timid politicians who will canvas on his behalf to sway even more to the dark side, coupled with a way-too-old competitor, I am not so confident that he won't be the next president. Keeping in mind, all that stuff about his university, steaks, racism, sociopathic tendencies, "diverting" funds from contributors and charities for his personal benefit, denigrating war heroes, etc etc etc, was well known by those who voted him in the first time.
It seems choosing a candidate these days isn't who's the best of the best, but who's not the worst of the worst.....
