Debate on Feb. 21

I am an admitted political junklie, but even I have to say that a debate this early is insanity.
Here are the committed attendees:
Sens. Hillary Clinton
Sen. Joe Biden
Sen.Chris Dodd
former Gov. Tom Vilsack
Gov. Bill Richardson
former Sen. Mike Gravel

Obama has not yet committed.
Also, where is Clark and Kucinich? Not that I'll miss them, but...
