Head to head when not really a choice at this time are fairly meaningless. Cruz is only known by 77% of Republicans so he is not known at all (really) with the public at large. His head to head with Clinton is totally meaningless.

Cruz was behind Hilary Clinton by a massive 24% a few months back when most voters didn't know him and everyone knew Hilary Clinton.
After the very high ratings debates, a lot of America's and have come to know and like him. The more the voting public have gotten to know Ted Cruz, the higher his polling numbers have gone. With only 77% of GOP voters being familiar with Cruz, it's pure upside.

In other words, polls mean exactly what you mean they say, no more and no less?
