Lieberman hours away from his Zell Miller moment

The Caucus's Kate Phillips:

Senator Joseph I. Lieberman’s speech tonight will likely be a testament to his deep alliance and friendship with Senator John McCain, but it also will likely fray even further — if not sever — his longstanding affiliation with the Democratic Party.

One would hope. There's been rumblings about Harry Reid stripping him of his committee assignments or whatever but the slim Senate majority created a disincentive to antagonize him. As we get closer to an election that's almost certain to result in more than 49 proper Democrats, and as Lieberman prepares to speak at the Republican convention, where he is sure to accuse Obama of treason and extol the manly virtues of John McCain, I think it's time to start treating him as hostile.
