CBS is calling Clark the winner in Oklahoma.
Kerry won big in North Dakota, New Mexico, Delaware, Arizona and Missouri.
Edwards in South Carolina.

I’ve got to consider this further, but right off the cuff, and in great need of sleep, I’ll say this:

Clark’s win in Oklahoma, coupled with Kerry’s coming in a distant third there, along with Edwards winning big in SC, means tom me that Kerry won’t win in more conservative states in the general election.

No argument that Kerry will win this nomination, barring Hillary leaping in, in an attampt to save the General election for the Democrats. Which may happen if this middle America rejection of him continues.
