I think that really kneecaps the Biden ministration in a significant way.

If he comes out and throws cold water on this, then I don't think it goes anywhere.

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.

No, their problem is Anderson, he's got more support back in their districts in their states than they do and that gives him enormous -- it gives him enormous leverage against them.
