After NY, Cruz will likely join the Kasich club

And if it does go to a 2nd ballot, why should Cruz get it?

Because he's completely dominated the delegate selection process?

Trump has completely dominated the primary process; why shouldn't he get it?

Because he hasn't? He's just gotten a bunch of weak pluralities.

I like Cruz.  But Cruz is going to have a rough time in the next hew weeks.  Meanwhile Trump will be winning primaries.  The GOP may find that the best way forward is to bite the bullet and nominate Trump.  Paul Ryan is refusing to be the nominee.  If Cruz had won a lot of southern states, then there would be a stronger case for him.  Look at Arizona, Cruz got trounced here in this GOP stronghold.  I really think Cruz has a weaker hand than many have been saying.
The big question is how many delegates will Trump have going into Cleveland.  Right now he has a big lead. And it is about to get a lot bigger.

Cruz would have won a lot of states if Rubio wasn't splitting votes with him.

Rubio's base has gone mostly to Cruz.

I will add I don't think the GOP has a great path to take, no matter what happens a significant chunk of people will be upset.
