Every Fox anchor and analyst seems to be reading off the exact same script, claiming massive momentum toward Rubio, that everybody they talk to on the streets of Iowa are switching from Trump and Cruz to Rubio. Then they drag out Frank Luntz and his paid actors playing the role of a focus group to parrot they same line, they are all switching to Rubio because Trump and Cruz are too mean, dishonest, whatever. Funny thing is Rubio hasn't budged in any of the recent polls....
And the losers will be claiming tomorrow that, well, Iowa never is a very good predictor of who wins the nomination, so Iowa really isn't that important in the overall scheme of things.
All Iowa has ever really served to do is to winnow the field. It doesn’t determine the ultimate winner.
The same will be true tonight. The vote will be a death knell for many candidates. Some of them will even realize it. ;-)
