David Gergen: “This backing-and-forthing is -- is causing a credibility gap.”

I think this the very idea that in 2024, we may have two men running against each other Biden and Trump, who would both be in their 80s if elected, that it too is enough to say, well, what are we doing here?

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.

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

He is going to hand Joe Biden a country more divided than it needs to be by trying to de-legitimate an election that was clearly won by Joe Biden.
