Perhaps you have seen this, I did not see a diary on it, but here is one of those "elitist east coasters with an education"'s view of the exit polling issue.

A thorough job with explanation of the statistical tools and discussion of the historical accuracy of exit polls.
He ends by saying, "systematic fraud...is a premature conclusion, but the elections unexplained exit poll discrepancies make it an unavoidable hypothesis, one that it is the responsibility of the media, academia, polling agencies, and the public to investigate."
I think he might have mentioned one of the candidates as well.
Update 11/12
A note from Dr. Freeman in response to my offer to post his comments.
"Just tell them that I appreciated reading through the thread and that I'll address the questions of stratification and clustering in my next revision, but that I have 470 emails in my inbox just from yesterday alone, and about 20 calls from the press.
Steve"
He also sent an updated version if anyone can let me know how to get it on-line I'd be glad to do so.
