From NBC's Domenico Montanaro
Rep. Joe Sestak (D-PA) is known by some to be very ambitious. Perhaps some of that ambition was showing when he said today that he was going to "wait and see" on whether he'd support Republican-turned-Democrat Arlen Specter in a Democratic primary.
Video: Saying he found himself more and more at odds with the GOP philosophy, and that he didn't want his record decided by the Pennsylvania Republicans, Sen. Arlen Specter announces he will run for re-election as a Democrat.
Sestak, a former two-star admiral elected in 2006, thought to be considering a 2010 Senate bid of his own, called Specter's decision a "good thing" for Specter, but not necessarily for Democrats or Pennsylvanians.
He told NBC's Andrea Mitchell on MSNBC that there are two things to consider:
1. "I ran for something, not against something." Sesktak said people should ask of Specter, "What he's running for?"
2. He said former President Bill Clinton reshaped the party for the better -- something Sestak said he would have liked to have seen Specter do for the GOP.
"I'm going to have to wait," Sestak said on whether he'd support Specter. "If the alternative is Toomey, that's one issue."
But he went on to say Specter's decision was shaped by politics. Specter, by the way, admitted as much at his news conference. He talked about seeing his own polling on Friday and expressing frustration with the state party and Republican base. He unloaded on the Club for Growth for costing Republicans elected officials by running people that can't win in general election or forcing people like former Sen. Lincoln Chafee to spend too much money in primaries.
"Is that the type of individual we want," Sestak asked of Specter, adding, "I have to see" what he's running for, "not that he can win, but that he's running on principle."
