This was the year for the R's to be practically invulnerable in the Senate as most of our seats were safe. 2008 is when we may be screwed because in that year, the gop has lots of vulnerable seats and the rats have very few.
You are 100 percent true! 2008 we have 28 seats that will be up for reelection and Democrats have 12. Plus we need a good conservative Presidential candidate or who know what will happen.
I thought it was 21 Republicans and 12 Democrats up for re-election in 2008.
