Lieberman is scum, still....scum we need for a couple more months.
Not any more; it's now too late to rearrange majority/minority status and committee leadership this session. This means that Lieberman could now announce he's caucusing with the Republicans, and the Democrats would still control the Senate.
Why is that?
Unlike the organizing resolution of January 2001, there was no clause in the resolution of January 2007 that allowed for the Senate to be reorganized if a member switched caucuses. From the outset, the Democrats would always control the 110th Senate.
(I worded my previous post incorrectly - it implied that some kind of deadline had passed.)
