His delegate support isn’t nearly so soft.
Meanwhile, Trump supporters, many handpicked by the establishment, will bolt by the hundreds after round 1.
That’s the point. Hell, that’s the race.
Yes it is very soft, as the article points out, and the GOP is well aware of. But my original point was that Cruz would have no one marching in the streets to save him. Enthusiasm for Cruz is so low he's literally having volunteers/staff attend rallies in order to boost numbers, while Trump gets 7 thousand people to show up with 1 or 2 days advance notice.
If Cruz doesn't have the People siding with him, he simply doesn't have anything at all. No one will be protesting to save Cruz at the convention and no one will be going to bat for him. He'll be abandoned even by his surrogates, guaranteed.
