I really couldn't care less about his shortcomings as a person, though he obviously has some huge character flaws and weaknesses that make me question his abilities as a leader.
What I do care about: he seems to know next to nothing about anything outside of the business realm. The debates have been an embarrassment. He says nothing about anything, because he knows nothing. Just makes it up as he goes. I'm OK with a morally-flawed person in the White House - hell, that describes most of our Presidents anyway - but this guy is a moron who only appeals to the uneducated masses.
