CNN exit polls showed Kerry winning in Florida, Ohio, and Pennsylvania. Early returns have Bush leading in 2 of the three. If he wins them, is it because the exit polls were wrong? Or could it be that the fix was in? Studies of results where DREs were used will be very interesting.
[edited 11/6 to correct the name of the network whose election polls showed Kerry winning in Ohio and Florida until they changed them - the next morning - to agree with the puzzling results.]
