Frist is going to win the Repub. nomination (and if he does, Dems are so screwed). Just a prediction.
Don't understand, Bayh would hammer Frist (that said it could be a pretty darn dull race)...
...indeed Warner, Richardson, Rendell, Kerry, Landrieu even Feingold would all be competitive facing Frist.
If it was not for the dynasty tag "Jeb" Bush would be the GOP strongest candidate instead Bill Owens, George Allen and Mark Sanford would have to be the front runners as things stand though Hagel would potentially do as well as McCain though it would be unlikely that he would be able to win the GOP nomination as he remains outside of the Republican establishment.
Indeed the more I think about it (and someone mentioned this earlier) Sanford may be the strongest Republican candidate.
