Here's the complete exchange with Chris Matthews:
Chris Matthews: What's the heart of darkness you discovered in him? Something that is so bad that you don't want him to win at all, even at the cost of the other side winning? What is it?Welp!
Mike Murphy: Well, I've never been a fan—
Matthews: I know, but what is the evil you found in him, something like evil that you found I think?
Murphy: He fails my commander-in-chief test. I think he is a stunning ignoramus on foreign policy issues and national security, which are the issues I care most about. And he's said one stupid, reckless thing after another, and he's shown absolutely no temperament to try to learn the things that he doesn't know, and he doesn't know just about everything. …The guy has a chimpanzee-level understanding of national security policy.
