If Trump goes well over the 1,237 pledged delegates from the Primaries, and at this point it is very likely that he will, then those who are pledged on the 1st vote to vote for their candidate will put him over the top.
Especially ow that CNN is showing Trump with 52 total delegates likely in PA (and it is likely that that number will go higher, probably over 60 before all is said and done and once they vote at the convention):

Current delegate count according to them, and I have found them to be fairly accurate is:
Trump: 991
Cruz: 568
Kasich: 154

I expect Trump will go well over the top (probably by 50 or more delegates at this point), on June 7th.
If Cruz is interested in the GOP nominee (without any e) winning in November, then he needs to concede next week after Trump (in all likelihood) takes Indiana.
I pray to God that is what he will do. He has the power to:
1) Unite the party by so doing.
2) Deliver a huge blow to the GOPe by so doing.
3) Set up for a big GOP November win.
My Open Letter to Ted Cruz

I say all of this as one who has diligently supported Cruz...but recognizes the truth of the situation and the absolute need to defeeat the Dems in November.
Jeff, he should have conceded this week after tuesdays landslide.
I have doubts that he will ever concede. He is showing how absolutely stupid a politician can be.
If he insists on dragging things out until the convention he'll be damaging not only the party but any future political aspirations he may harbor as well. Committing political suicide in this manner will only prove that he's either completely out of touch or has been acting under orders all along.
