Senate Democrats are ready to give him the boot, says Bob Novak:

Despite assurances to the contrary from Senate Majority Leader Harry Reid, Democratic insiders are certain Sen. Joseph Lieberman next year will be kicked out of the party’s caucus and lose his Senate chairmanship if he addresses the Republican National Convention in St. Paul, Minn., as planned.

This is the handiwork of the MoveOn.org/DFA/Howard Dean wing of the party, which backed Ned Lamont’s primary challenge of Lieberman in 2006. “Progressive” Democrats may stridently defend the right of dissent in wartime, but they would not tolerate a prominent Democratic senator who refused to march to their anti-war music.

Perhaps Joe should get together with Zell Miller and form the Ex-Democrat Party. Maybe they can persuade Hillary Clinton and the PUMAs to join them.
