No, the Republicans won’t be a unified party. When the leading candidate has a large and rock-solid minority of about 37 percent, which means 63 percent of the party is voting against him, it means a lot of people are going to leave very mad.

If Trump loses, he’ll walk, and lots of his voters will walk away with him, though whether he’ll run on a third party line is unclear. If he wins, there will be a third line on the ballot, partly to protect the down ticket candidates, and there may also be another Republican candidate. If Trump loses after multiple votes, his supporters will claim the moral high ground as he had more votes than anyone else going in, while his opponents will claim that many more people had voted against him, and it was right that their interests prevailed.
