I think that [Chris] Christie`s endorsement is, you know, it`s a sign that - you know, he is who we thought he was in so many different respects. He`s someone who ambition is the only thing that I think is bigger than his appetite.I think in this case, it`s a situation where he saw the one guy who he thinks he can maybe get a cabinet post with if he wins in Donald Trump. I think, you know, he kind of went out the door doing a number of favors in beating up Marco Rubio the way he did.

Whether that's questioning the dominant opinion of the day, the conventional wisdom of the day, or whether it's questioning the policies that come out of Washington, or out of our government, generally, I think media's job is to look at it and say, "What's really going on here? What's the story behind what you see?"

I think this is a moment where Donald Trump recognized the Republican establishment was much weaker, the party leaders were much weaker than they thought they were in terms of being able to dictate any outcomes.

Few years ago [Donald] Trump was being roasted by Comedy Central. They always have rules about things that you can't joke about. Donald Trump's rule at that time, the only thing that you couldn't joke about was a suggestion that he has less money that he claimed to.

Donald Trump came along and spoke in a language that speaks directly to a portion of the Republican base with what they want to hear. I don`t think that he actually has a very significant ideology.

I think it`s a message of economic nationalism. It`s obviously one that has bubbled up before in certain pockets, but it`s never been the sort of powerful phenomenon that it is today.
