Other possible flips would be Connecticut (though I think Dodd's problems will be behind him at election time), Louisiana (Vitter is weak, Melancon has a shot to beat him), North Carolina (Burr is unremarkable), and Delaware (if Castle runs). I'm least confident that Ohio will flip, but fairly positive on Missouri (appears to be the better candidate) and Kentucky (Bunning. Enough said.) It'll be close in NH, but I think that it'll still flip.
And if Grassley (Iowa) and McCain (Arizona) retire, those are good shots at a flip.
If Hutchison (Texas) leaves early, the Dems have a longshot there too, if Bill White or John Sharp is the nominee.
