Nah, I don't know the #'s. I'd assume that the rino senators (mccain, snowe, chafee, maybe more) would be siding with the dems. However, the trend of picking up more congressional seats each election might help quite a bit towards accomplishing this reform after the '06 election.
Up for Senatorial Reelection in 2006:
14 Republicans
17 Democrats
1 Independent
so it's time for Jeffords' payback! haha!
Looking at who they are, i see about 5 or 6 Democratic seat we could possibly gain, and about 4 we really need to worry about defending.
