Trump's birtherism regarding President Obama cannot be ignored as contributing to our present nastiness! He has taken an active role in feeding this national division for his own benefit. Although he is not the most intelligent person, he does have a viscous animal cunning and recognized a great opportunity for self enrichment and the feeding of the big hole in his chest where his heart should be, with the roar of an approving crowd. That's really what he craves, the cheers of a big admiring crowd. I'm pretty sure he'd be bored with the duties of President in about 10 minutes when he found out you have to study, read, investigate, listen, and think over decisions very carefully; with no cheering crowds. When a President screws up, thousands can die! The fact that so many place any trust in a obviously defective, narcissistic, and childish man such as Trump scares me more for the future survival of the USA than any other threat!
