I just got off the phone with Sen. Arlen Specter's (D-PA) campaign manager Chris Nicholas, and he didn't have much to say regarding Rep. Joe Sestak's plans to run for the Senate.

Nicholas pointed out to me that Sestak's sister, who is also a campaign staffer, appeared to indicate that Sestak has yet to sit down with his family to make a final decision.

"There's nothing to react to," said Nicholas. "There's no announcement here. So we have no comment."
