If the Dems get it to 50/50 we all know who will defect...
We don't need to worry about Democrats having 50 U.S. senators. I think that Republicans will gain seats in FL, MN, and NE and that the Democrats will gain a seat in PA. In VT, an independent, Sanders, will replace an independent, Jeffords. Therefore, in 2007, the Senate will have 57 Republicans, 42 Democrats, and an independent.
