David Gergen: “I think Donald Trump is going to emerge very differently from Nixon and Clinton. He's not going to be contrite. He's not…”

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

I think the signs are just as Margaret says. They are saying that he is increasingly interested. Strikingly, Anderson, his interest seems to intensify when he sees Biden in trouble.

It is vital that as President, tell his base and tell the whole country that he believes Joe Biden is a legitimate President, that he has not been put there by fraud.

It's very, very big. Not legally, but politically, it's a very, very big deal.
