That's the Talking Points Memo headline on this new development that also comes via Greg Sargent:
Sestak cautioned that Stern didn’t directly address the 2010 primary. But he said the meeting went “great,” strongly suggesting that SEIU is seriously considering supporting him or another primary challenger to Specter. “It was very clear that there were a number of issues we agree on,” Sestak said of his much-anticipated meeting with Stern.
Sestak also confirmed that he’d almost certainly get in the race if Specter doesn’t show a major ideological change of heart. “If he doesn’t demonstrate that he has shifted his position on a number of issues, I would not hesitate at all to get in,” Sestak said.
