This is a bombshell from the political world. I believe that means Al Franken will make Obama filibuster-proof. Obviously, this is very bad news for Republicans. I suspect that the deal is that Rendell and Casey will pull out ALL the stops to get Specter re-elected too.
Confirmed that Sen Specter will become a Democrat (but he is still against EFCA as noted in his statement).
The GOP is dead in the the blue states for the foreseeable future.
I am with Kos, I see the Maine senators potentially switching now as well. They will have no legislative power anymore, so why stay with the GOP in a state where it will be easier to get elected as a Dem?
