Interviewed on MSNBC, Joe Sestak just said he still might run against Specter.
He wants to see what Arlen Specter stands for. This is hugely important. Time to see what Arlen's plans are. If Sestak is sincere about this, he is doing us a huge favor.
Everyone needs to keep in mind that Specter is significantly to the right of Ben Nelson. This is way, way beyond even Lieberman. Replacing him even with a New Democrat like Sestak would create roughly a 50% shift in voting habits, according to Progressive Punch. No other Democratic primary in the entire country has the same potential for offering even close to such a large shift to the left in voting habits.
Update: Specter just said that he won't invoke cloture on Employee Free Choice. So much for the theory that he would vote against the bill, but allow cloture.
