You might have spoken too soon. There are 57 Senators in the 111th Congress's D-I Senate caucus so far, compared to 40 in the R, and three races are still undecided. I suspect, that Al Franken will ultimately win one of those races through Democrat treachery, at which point I will have to start calling it the Roman Senate (during the last days of Rome, of course).
I expect Chambliss will take Georgia. He has over a 100,000 vote lead with 99% reporting.
Stevens has a very narrow 3,500 vote lead in Alaska and I expect he may well hold it.
My guess is 42 GOP, 58 DNC, maybe 43 to 57, or also maybe 41 to 59.
