Hilary Rosen is now at the center of a firestorm after commenting on CNN last night that Ann Romney, “never worked a day in her life.” On Twitter last night, Rosen doubled down on her attacks even as key members of the Obama campaign asked her to apologize.

After combing through her history of political punditry, however, it appears that Rosen rarely thinks that any attack made by a liberal or a Democrat is unfair – not even a tasteless joke from liberal comedian Wanda Sykes.
