I don't know about Clark worrying Bush so much. Are you talking about how the states holding primary elections in two weeks will vote in the general, or how they will vote in the primary?
Clark is the only one that has Bush scared.
It depends how one interpets the Iowa caucus--if one can--Kerry getting it was a complete surprise to me.
If Iowans selected Kerry instead of Gearhart (favorite son type) or Dean (firebrand), as more on the basis if of beating Bush, rather that who they liked, it could mean that the other states may pick the best anti-Bush dem....... rather than who they "like"......
