Ouch. That one is going to hurt. Last summer, when we filmed Senator Arlen Specter and Congressman Joe Sestak at the Netroots Nation conference, I remember commenting to Mitch that Sestak seemed to have kid gloves on when it came to Specter's Republican credentials. We concluded that they were likely holding off until closer to the election. I would say we are officially closer to the election now.
