David Gergen: “Joe McCarthy was one of the great villains in American history.”

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.

Sadly, you know, I think for a variety of reasons he should not. I just, I don't think either Trump or Biden should be running.

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

I think the evidence is still coming in that this country is deeply divided.
