Ex-Republican senator compares Romney to porn star

On MSNBC's "Morning Joe" today, former Pennyslvania senator Arlen Specter happily lit into Mitt Romney, jokingly comparing him to a porn star: "The Republican Party has moved so far to the right, you can't recognize Mitt Romney. What Mitt Romney will appear in October? Mitt Romney has changed positions more often than a pornographic movie queen." The inflammatory comparison is the latest put on Romney by a fellow Republican trying to define his campaign, coming exactly a week after a Romney adviser compared his boss to an Etch a Sketch.
