When Stephen Colbert invited newcaster-turned-education-reformer Campbell Brown on his show last night, he unwittingly unleashed a firestorm of controversy and, some say, distanced him from his liberal brother-in-fake-news, and fellow Viacom employee, Jon Stewart. Several hundred of Colbert’s leftwing fans protested outside of his Manhattan studio before the taping, and thousands more took to the blogosphere, decrying Brown as an elitist union-buster and accusing Colbert of being “a sell out like the rest of them.” “Maybe Colbert ought to watch the Jon Stewart show to learn about education issues!” wrote one commenter.
