From Howard Kurtz‘s chat today:

Question: I enjoyed the article today on Stephen Colbert‘s new show. One thing struck me though, and I’ve heard it before, that MSM reporters have said to him (or others on the Daily Show) that they wish they could say the things they say on the show. And Colbert wonders why don’t they? Maybe you can help answer that question, why don’t they?

Howard Kurtz: Because they’re wimps?
