Sorry but I don’t think a CNN Exit Poll is very compelling data. I think it has been proven that Exit Polls are not very reliable. The Magic 8 Ball says “Try Again.”
What sort of data meets your criteria? Actually if anything I think that 2006 CNN exit poll oversampled the conservatives. What is clear is that the MSM is skilled in the art of conservative turnout depression by the timing and nature of coverage of news stories such as the Mark Foley scandal. Expect more of the same next year. If Hillary is the nominee, expect much more.
