Even if we lose a couple seats in the Senate in 2006, we still have a majority! I don't agree with the analysis that we are exposed in 2006. I think we will pick up 1 or 2 seats in 2006 but even if we lose we still control the Senate.
You get dangerous when the Dems pull within 2 or 3 of control. Defections are bound to occur...or at least overtures. If the Senate remains as polarized as it is now, I could see severe infighting in the majority.
