FWIW, the nominating process is not over. The more Trump whines about the process being rigged, the GOP being deceitful and the need for Cruz and Kasich to get out, the more it is becoming clear that Trump knows if he can't get to 1237 before the convention he won't get the nomination. All the attempts to intimidate delegates further supports this.
In 2 months we will know. If Trump doesn't get the nomination are his supporters going to call for unity behind the nominee? I doubt it.
In two months, if Trump DOES get the nomination, will YOU call for unity behind the nominee?
