Trump is a salesman and his rhetoric is merely a pitch. By stirring up the anger of the US populace, he distracted them long enough to get their votes. He has adopted this role deliberately.  While you're wasting time on his mental status, you're not covering the biggest internal terror risk in the USA, white nationalism and other supremacy and extremist groups. Those groups are enforcing his new policies informally in every town and state in the USA. Steve Bannon has his fingers on their pulse. The billionaires who have teamed with Trump to rule have come from energy, education  and finance. Focusing on the individual will not help you work a political solution in the USA. A coalition of right wing interests has taken over the White House. Trump is their immoral pitch man. Move on and get busy rebuilding the Democratic party at the grassroots level.
