CNN screwing the pooch again?

CNN just declared Kerry the winner in Winsconsin based on their exit polling. Wolf Blitzer delivered the news.

However, 33% of the vote has been counted, and Edwards and Kerry each have about 45500 votes, with <200 votes separating them. Either they know the counties which have yet to report, and those are really skewed, or they're running a replay of 2000.
