David Gergen: “I think Mitt Romney remains the most speculated about and possible.”

We're entering some kind of the most dangerous days of Donald Trump's presidency. He is erratic.

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

You can stand up and say we shouldn't be doing this because it's unconstitutional. Therefore, I never have to come to say whether I agree or disagree whether he incited the riot.

He is a leader there's no question about that. But I think he's a bad leader. I think he's leaving his people into, he's leading the country, especially into a very bad place.
