How many times do we have to Dump Joe Lieberman? We booted him out of the Democratic Party in the 2006 primary, when Ned Lamont shocked the political establishment. Despite the humiliation, Lieberman stayed in the race as an independent and beat Lamont with Republican votes.

Senate Democrats were kind enough to let Lieberman caucus with them and chair the Homeland Security Committee. How did he repay their kindness? By campaigning against Obama and for McCain, including a prime-time speech at the Republican convention.

Last week, Harry Reid told Joe he had to give up his chairmanship if he wanted to stay in the Democratic Caucus. Lieberman refused and is appealing to the Senate Democratic Steering and Outreach Committee, which determine committee chairs.

You can use our call tool to reach the 19 Democratic Senators on the Senate Democratic Steering and Outreach Committee and ask them to relieve Joe Lieberman of his gavel before the start of the next Congress.

Update 2: Brave New Films says Lieberman Must Go. Go there and call your Senator.
