A place where kerry has higher potential support is not good news. Those numbers are outside the margin of error. Like the site said, if kerry has better GOTV, he's got more to draw on. For me, a poll that shows Bush up 50+ to 45 or 46 would be nice.
I'm happy with last 2 days of trends though.
Instead of being concerned about "potential" support focus on the good news that his actual support is weak.
Ohio will go to bush.
