According to Dave Wissing's page below is the ARG South Carolina Poll.
Frankly I think whichever one of Kerry, Dean, Clark and Lieberman is smart enough to blow off South Carolina (it's an expensive state they are all fighting over) to spend the equivalent resources between oddly practically uncontested Missouri and the other 2/3 states will be the one to exceed expectations on Mini-Tuesday.
Missouri has more delegates at stake, but all of the campaigns seem to be stuck in pre-Gephardt dropping mode.
Dean in particular should be focusing his resources here.
