If we are so desperately deluded and horribly unlucky as to have Trump for our nominee, I will vote for him.
Of course, I'm already on record as saying I'll vote for the Republican nominee unless it is Bush. Then it will be a third party or a no-vote on the top line of the ballot. I just don't think I could let myself vote for Jeb.
What we're experiencing now is an intramural squabble. In the end, it will result in the strongest nominee emerging. We'll unite behind that man (or Carly) in the end. Bet on it.
