They get hysterical, and they start ranting about public executions.

Chris Matthews: I have my own views of the word "socialist," and I'll be glad to tell them -- share them with you in private, and they go back to the early 1950s.

I have an attitude about them. I remember the Cold War. I have an attitude towards Castro. I believe that Castro and the Reds had won the Cold War, there would be executions in Central Park and I might have been one of the ones getting executed. And certain other people would be there cheering, okay, so I have a problem with people who took the other side.

I don't know who Bernie supports over these years. I don't know what he means by socialism. One week it's Denmark? We're going to be like Denmark. OK, that's harmless. That is basically a capitalist country with a lot of good social welfare programs. Denmark is harmless.

Chris Hayes, MSNBC host: He's pretty clearly in the Denmark category, yes.

Matthews: Is he?

Hayes: Yes.

Matthews: Are you sure? How do you know? Did he tell you that?

Stop Bernie. That is the focus right now and in Democratic circles in Washington, that's really all they're thinking about.

They fear Bernie more than Trump. But the question is, how do they stop him? It is still a democracy after all.
