When a party has had enough votes to end a filibuster on its own, we have not been able to find a single time in history where members have joined with the opposition party to filibuster a bill.

So who is the Senator willing to stand up and say they will take this unprecedented move, betray the President, the Senate leadership and their own caucus, and do this?  Who is willing to say they are going to make history?

Not Joe Lieberman, because Mike Stark asked him two days ago

I just have one question for the veal pen. Where is there even one, and I mean one, member of the Democratic caucus who has said they will join with Republicans to filibuster it? Come on, you’re cheering for a sketchy plan with only a one page “white paper” that nobody has seen. Surely you’ve thought this through, and are convinced it is a necessary step to keep Democrats from voting against cloture.

So who is it? If you’re acting out of political necessity, who is this mysterious Senator (or Senators) telling you they’ll take this bold step, who don’t have the courage to say so in public?
