Russ Feingold of Wisconsin, recently defeated in his Senate re-election bid, has been mentioned.

I don't know that such a challenge from the left would be a good thing for Republicans. The challenge would surely fail, and would let Obama "triangulate" to an extent, and even try to pass himself off as a moderate.

LOL. If the guy can’t even win in his own state, I’m not sure how serious a presidential candidate he can possibly be.
