David Gergen: “I think right now they favor John Kerry as the next secretary of state.”

He is a leader there's no question about that. But I think he's a bad leader. I think he's leaving his people into, he's leading the country, especially into a very bad place.

I think we're in an unsustainable path. It's compared to being in a car on the edge of a cliff, and middle of the night with it with a rainy and no headlights.

I think a lot of Americans do see it as disqualifying. And they're worried about it.

You can't out-Nixon Nixon very easily, but Donald Trump has.
