And cruz only won because of beck's endorsement.

What you mean her endorsement speech that was so nonsensical that even Trump was wincing?

Cruz had the ground game. Trump had virtually no ground game. However, Cruz’s ground game was spent on one state on a caucus system. Primaries are a different matter. I have heard that Bush could win the New Hampshire Primary if he drew decent crowds but, he doesn’t. Actually, I think Trump will win in New Hampshire. He is packing in crowds already at 5,000 a rally.
