The only way to unify the party is for Cruz and Kasich to drop out and stop their insane quest to let Hillary win.
In the end, that's all they are doing at this point.
I disagree. The only person that can unify the party at this point is Donald Trump. He needs to take the initiative. Until he has 1237 committed delegates, the race is still on. We've had contested conventions before. After the contested conventions, the party unifies around the winner. If Trump is unable to get 1237 delegates before the convention, then he is going to have to convince someone else's delegates to put him over the top. If he can do that, then he will have won "fair" (DT's favorite word) and square.
If he can't do it, then he doesn't deserve the nomination.
Surely you aren't afraid that he can't convince enough uncommitted delegates to come over to his side, are you?
Do you think he's pissed off that many people in his rather unusual campaign?
