Mystery Pollster to Democratic Bloggers: Stop Going to Coffee-Shop Poetry Readings and Take a Stats Class
Mystery Pollster Mark Blumenthal has a very extensive post on exit polling. You should read the whole thing if you want game on all the conspiracy theories, but the money graf comes at the end:
Absent further data from NEP, you can choose to believe that an existing problem with exit polls got worse this year in the face of declining response rates and rising distrust of big media, that a slightly higher number of Bush voters than Kerry voters declined to be interviewed. Or, you can believe that a massive secret conspiracy somehow shifted roughly 2% of the vote from Kerry to Bush in every battleground state, a conspiracy that fooled everyone but the exit pollsters - and then only for a few hours - after which they deliberately suppressed evidence of the fraud and damaged their own reputations by blaming the discrepancies on weaknesses in their data.
