The Democrats have a chance at defeating Senator Dole of North Carolina. Senator Warner of Virginia who has been whining about how he fillibustered his own bill could be vulnerable, or could retire. If Domenici retires, that race should be competitive.
All three of those seats are very prime targets for Democrats. Especially if John Edwards were to win the Democratic Nomination for President, that would, imo, put North Carolina and Virginia as toss-ups.
Oh, don't get my hopes up?
Who do you think might run in OK? The AG? Young Boren?
I know there are lots of Brad Carson admirers out there but if you actually saw him speak, he kinda has a charisma deficit. I think a candidate with a little charisma and a solidly moderate/conservative record could give Inhofe a run for his money.
Also, I'd note that OK's other senator has said and done a lot more to endear himself with OK's populist elements than that stupid, uninspiring, corporate-shill Inhofe.
