And the Democrats will lose one, to Leiberman. That'll make it 54-44-2. Bad new for Democrats, 10 seats behind in the Senate.
However, Lieberman would be expected to vote as a conservative Democrat on the WOT and Iraq. On the other hand, there would still be a few RINOS there whose votes are iffy in quite a number of areas.
Still, the bottom line is that the GOP will most likely maintain organizational control of the Senate.
