I hope Hillary will stay in the Senate, Edwards will succeed Dean as DNC Chair, and Wes Clark will wait to be appointed by someone that can actually win an election, besides a three-way-tie in Oklahoma. I just hope Kerry does anything but run for President (it's not like he'll get the nomination anyway). I also hope Bayh and Warner work something out before they split the moderate vote.
I really think it will be Warner (currently) who wins the party nomination. If someone else from the party rises up in the next year, he might have a challenge on his hands. As far as Edwards taking over for Dean, that would definitely be an improvement, especially given his speaking skills.
