David Gergen: “Donald Trump's disapproval rating today at Gallop went hit 60 percent.”

If he comes out and throws cold water on this, then I don't think it goes anywhere.

If he had a receptive audience, and I will tell you, when everything -- when all the facts were to come out, it would be like Nixon and the tapes.

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