I'm afraid there's just no evidence for that.
Ted has a pretty narrow appeal - mostly on the staunchly conservative, Christian, Anglo, right. There's no buzz for him in any other quarters of the voting public.
You can't see that from inside the conservative bubble. You've got to go lurk at places where people of all persuasions comment publicly. In those places, when Ted is mentioned at all, it's usually wisecracks or dismissal. I've seen very few non conservatives post supportive statements about Ted.
On the other hand, I can't tell you how many times I've seen posters claim that they're switching sides to vote for Trump. It's not an avalanche, but it's a steady enough flow to take notice.
It isn't Cruz's appeal that I expect would win him the election. It's the fact that Hillary is such a horrible witch, and has such an awful background, that once all her scandals start coming out, people will remember how much they hate her.
That's if she doesn't stroke out from apoplexy as she is being presented with her nasty past.

Not so. Cruz won 17-29 year olds decisively in S. Carolina. He also won among people for whom the Supreme Court, national security and ‘shares my values’ are uppermost to them.
