This clip of Ted Cruz from the Values Voter Summit shows why he is not to be taken lightly:
Despite being interrupted several times Cruz was not bothered by it. In fact, he seemed to work it into his act to win over the crowd the way a comic would dismiss a heckler.
He may have been taken off the Christmas card list of Norquist, McCain, and others in the GOP but Cruz is building a real following with key segments of primary voters. As I have said before, no matter what they say in D.C., Cruz is a real force in the 2016 GOP primary.
