Misplaced pride. I guess people that didn’t leave the house that November to vote feel vindicated.
He was an empty suit candidate who really did choke vs Candy Crowly and thought he would win by default.
I wonder. He certainly didn't choke when brutalizing his Republican competition in the primaries. Keep in mind that Romney refused to campaign against the "lower 47%". Perhaps Romney thought that campaigning against Obama was beneath his dignity.
Why is Romney being such a disgusting jerk? Trump fights like the people he has such disdain for. If one doesn't play by Romney's rules, he thinks of those people as beneath him on the superiority scale.
JMHO
It's just killing him.
You nailed it. Misplaced pride. He felt all his life he “deserved” the limelight, and now he can’t let it go. For all his vast personal fortune, he is unable to truly enjoy it, because his ambition blinds him.
