There have to be consequences

Harry, tell Joe Lieberman he can start rebuilding his Democratic cred by keeping his mouth shut and voting with you until 2010. Otherwise, he can go kiss Mitch McConnell's tobacco-stained ass.

Oh, and change the filibuster rule to 55. Put McConnell in the position of needing to win support across the aisle instead of simply saying nyet to everything.

At every moment, remind the Republicans that they are the ones who screwed collegiality. But don't let them screw you, too.
