BILL HEMMER (CO-ANCHOR): Go ahead and frame the argument that the president is making there from last night, sir.

NEWT GINGRICH (FOX NEWS CONTRIBUTOR): Look, I think Kim Strassel did a great job with the column where she said the choice is between the left and the crazy left, and the crazy left is winning. I watched the first night. It was amazing the level of anger that you got out of Bernie Sanders and Senator [Elizabeth] Warren. I mean, these are really angry people, and it was kind of amazing to watch them. It's the opposite of how people normally win the presidency. You go back and you watch Barack Obama with a big smile. You watch Ronald Reagan with a big smile. I don't remember us electing an angry president literally in my lifetime. And yet you have these people who were almost in a rage. You also had the fact that they're all drifting towards cloud cuckoo land. I mean, when you have a number of moderate Democrats on the stage -- and they'll all be gone soon because they're not getting enough support to survive. But they're on the stage and they're saying -- one of them said if we go down this road of taking away everybody's health insurance we'll be lucky to carry two states. Now that was a Democrat in the debate warning his follow Democrats that they could be throwing away the presidency. And I think we have to take that seriously.

And of course, the president is watching all this and he's exactly right, and he wants to stoke the fire a little bit about Obama. What's turned out is that President Obama is no longer radical enough for the left wing of the Democratic Party. So you're going to end up with Biden defending Obama while the rest of the party attacks him. The truth is, on things like deportation, President Obama deported more illegal immigrants than any other president in American history. In terms of the Affordable Care Act, which was not affordable, but it didn't cover everybody that left-wingers want to cover. And so you can go down a list and you realize there's a real fault line in the Democratic Party, and we're watching it play out in these debates.
