Formidable and newly minted MSNBC host Rachel Maddow went toe-to-toe with the National Review‘s David Frum Monday night, and it was pretty entertaining—just watch! He calls her and her show dumb and negative, practically. She calls his droll accusations stupid and misguided, just about. And while you might be wondering why Frum allowed himself to get stuck on a bitter point about the sarcastic, “unserious” media, don’t: he was jetlagged and grouchy. He’ll have you know he’s not really a total prick at all.
