Mr.McCain is not a nice man, and people do not vote, generally, for self-centered, mean SOBs.
If he's still teed off about the South Carolina GOP primary in 2000, that means this man has great talent for carrying a grudge. But that's all.
Carrying a grudge, as we all know, leads only to more anger and bad decisions.
he's actually a very thin-skinned narcissist
I agree with that characterization.
