I think not to count out John Edwards, he has been campaigning across this country as stated on his site for many others (if he had done that for his own campaign he would be far ahead of Feingold and right under Hillary):
"Senator John Edwards is committed to helping as many candidates as possible before November. He has already raised $6.65 million for Democrats and attended fundraisers for strong congressional candidates in more than a dozen states this election cylce."

I believe that after the November elections you will see the tide turn rapidly. IMO
One more opinion: this party needs to dump Bayh!
