It could be from all those White House parties. An active night life like that can really wear a psudo-president down.
Just last week (at Westpoint) the guy was speaking how important it was that the country be united.
One week he’s saying the Republicans better get out a Mop or a Broom and clean up the Mess they made to a excited mob, now he’s back to insults and barbs.
I’ve never seen anyone get that far in life that doesn’t take responsibility. People respect people that take responsibility for their part, this guy has a personality disorder and it’s starts with narcissism.
