NEIL CAVUTO (HOST): Even people who aren't big fans of Donald Trump were like stopped in their tracks, stunned. A lot of friends of mine who don't necessarily find Donald Trump their cup of tea, but boy, especially the New Yorkers among them, they were stunned and staggered by those remarks and some of them said, well who'd have known? Pat Buchanan, your thoughts on that.

PAT BUCHANAN: Well, I think you're right. I think what Ted Cruz was trying to do is what Jean Kirkpatrick did at the 1984 convention of the Republicans where she referred to San Francisco Democrats a number of times and people laughed and cheered, but you're right, Neil. When folks think of New York now, and what is the image? A lot of us think of the image as firemen running into a burning building and climbing up stairs to rescue people when there's a good probability those buildings are going to collapse on top of them, which is what happened. So, I think that it was a tin eared comment by Senator Cruz and I think he's going to pay a place for it and was Donald Trump's best moment in the debate and it's one reasons that a number of people say it was his best debate and he won it.

CAVUTO: Well, I've heard the same thing but a lot of people say, well not so fast on Ted Cruz, that he might be clever like a fox here. That this was his exact intention and to remind people in southern states that have little regard for New Yorkers. I'm not saying they're heartless when it comes to 9/11 but they do by and large accept the line that the senator raised about the liberal media Mecca, the bias, the clueless elite class on the coasts and all that and that's what he hopes to pounce on in places like Iowa and later when it gets in the southern states like here in South Carolina. What do you think?

BUCHANAN: I don't think it's working because Donald Trump is very, very strong in South Carolina, secondarily, Trump's support is really much more working class and middle class than it is wealthy elite New York types when you think of Wall Street and the hedge fund folks and the beautiful people and the folks coming to the rallies, they're enormous and they don't look like the beautiful people.
