We've had a never ending list of dysfunctional "leaders" with myriad personality disorder issues... and we have muddled thru. Let's review:
Kennedy was a sex and drug addict. Johnson was a low esteem Texas redneck, Nixon was a paranoid freak. Ford was a dumb shunkbear jock. Carter was nuclear peanut farmer with mommy issues. Reagan was a b-grade movie star idiot. Bush was wishy washy former CIA director. Clinton was a trailer park sex criminal. Bush II was just an unconnected simpleton. Obama was a consummate narcissist. Trump is probably our most disturbed President ever.
What's really amazing is that our Congress is loaded with the same sort of circus freaks.
