I get the impression that a lot of people are getting tired of debating the details of PPP’s methodology, but I think it’s worth flagging a few recent polls in Georgia, which nicely illustrate the questions about their methodology.
Last week, I wrote a long piece about PPP’s troubling methodological choices. Some people assumed it was a continuation of a fight the previous day between Nate Silver and PPP, but it’s not. And other people latched onto various elements at the expense of others. Many of those elements are important, like PPP’s baffling incompetence, or its decision to surreptitiously let the self-reported ’08 vote inform the racial composition of the electorate.
