Hillary will take over as Senate Minority Leader for Daschle.
Clark will vow to only serve one term because he wants to be the "outsider" candidate. Thus, if by some freak of nature Clark wins, he sets it up for Hillary in 2008.
He may say that now, but once he's the President, he might not be quite as controllable (I don't think he'll get elected, just hypothetical musing here).
BTW, whatever happened to Carol Mosely Braun? Her web site's still up, but I've heard more out of Jimmy Hoffa than her for the last month.
