TV satirist Stephen Colbert picks up a prestigious Peabody Award today. Colbert touts the Colbert bump, an advantage he claims politicians get when they appear on the Colbert Report. It turns out he's right. Also today, New York Times reporter Tim Weiner on the history of the CIA. He says it's been marked by repeated and persistent failure. And Rick Perlstein traces the fierce partisanship in contemporary American politics back to Richard Nixon. Plus, novelist Russell Banks tries his hand at history in a new book called Dreaming Up America.
