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.

The midterms really helped him. They transformed the race, best midterm elections for any president in 20 years.

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

I think it's going to take something usually unexpected or a dramatic change in his health or a prison sentence to stop him.
