Okay, I am half asleep, but here goes.
1. assuming no massive blatant fraud (if there is fraud--like vote flipping, Dems should only get 2 senate and 14 house...but I digress).
If no major fraud, 5 senate seats and 22 House seats will go the Dems way. I am being conservative (better than getting your hopes too far up). I think that 6 seats is a distinct possibility, but I am sticking with 5 for now.
