Mercifully, after New York votes in 1 week, the writing on the wall will be apparent to all but the most delusional Ted Cruz fanboys...
That's all he has left now. He can't win a majority of delegates, not in the Trump friendly states coming up. His only hope is to win over the GOPe at a contested convention.
His other option is to ally with Trump any block the GOPe, but that would involve accepting the VP slot (Trump has to be on top or no deal) and convincing Trump to give it to him.
That seems less likely every day.
We're going to have to listen to deluded Cruz supporters ranting about his "ground game" right up to the moment Trump gets an absolute majority of delegates or when the GOPe stabs Cruz in the back at the convention.
