Well, OK, your numbers seem pretty sensible, except I view Minn as a tossup. The GOP has a quite sensible alternative to Wellstone. I would give Thune slightly higher odds. I don't have a good feeling about Missouri though, unless Carnahan exudes lack of knowledge in debates or on the trial and messes up. She can push the rural thing versus the St. Louis corporate lawyer slicker.
Is there a possibility Inhofe can be tanked? He comes across as a distinctly unloveable personality to me. He seems wound up really tight. Both my moderate liberal brother and I have him on our least attractive senator list, putting aside, somewhat but not entirely, ideology.
I know of two polls on the Walters-Inhofe race. One showed Inhofe up by 13. Another showed him up by 8 (if I read it right, this may have been a typo in the Oklahoman.) Walters will have money.
