What to do with Lieberman?

I found a petition online to have Joe Lieberman removed from his chairmanship on the Senate Committee on Homeland Security and Government. I think that this is actually a pretty important issue for the Dem. senate to reconcile before Obama becomes the President. Joe had the opportunity to respectfully disagree with Obama and the democrats on several issues this campaign, but instead he choose to take every opportunity he got to make slimy claims that Obama does not "put the country first", and being the keynote attack dog at the Republican National Convention. I have no doubt that left in a leadership position, Joe will once again attempt to scam and screw over the Democratic party to further his own self interests and pursue his vendetta against the party that voted him out in the Ct. Senate Primary. Anyone interested in signing the petition go here:
