I have a total of nineteen seats changing hands between Election Day 2008 and the new Senate that will begin work in January, assuming no further changes, and for the time being assuming that Bennet, Murray, and Murkowski all hang on to win.
Those nineteen new Senators are a grand total of...wait for it...276 years younger than the 19 Senators they replaced. That's pretty dramatic! Of course, it's a tough fight against inertia, since the continuing Senators are getting older. Still, this will be the first Senate to turn back the clock in quite a while.
Hmmmm . . .
