Your thoughts=equal the same thoughts here. Cruz doing the leg work needing to be done as The Donald takes the incoming fire. If TRUMP wins the nomination and does not name CRUZ as his running mate, not only would I be sorely surprised, I’d be thoroughly disappointed in him.
GO TRUMP! GO CRUZ! ~ YOU WIN OR WE LOSE!!
I think it might have something to do with Cruz’s ambitions. If he wants to sit in the chair he would accept an offer as VP. If he was willing to serve as AG then a Supreme, I believe he would become an historical figure.
