NR is in the tank against Trump.
But, if on Tuesday the 26th Trump picks up another 100 delegates (and I believe he will, if not more), then he is going to be closing in on 950+ delegates.
That will leave him about 280 short...with still 500 more to go. I believe he will get the 53% of those he needs.
He has the only path to the nomination before the convention, and at this stage, short of a major fumble, I believe he is on track to get it.
This is why I, as a Cruz supporter, wrote the following:

Although Ted now has no path to the nomination prior to the convention, Ted does have the power to unite the party and drive the stake through the GOPe’s heart.
I hope he will.
Option 1 at least gives them a chance to salvage Congress (saving the Senate in particular is going to be tough, given that Team Red is defending many more seats than Team Blue this cycle).
