We all know pollsters get it wrong from time to time, but you have to hand it to Public Policy Polling for refreshing candor. After the results were in, the only major polling group to predict an Obama victory in Pennsylvania posted on its blog: ” … please do not call us or e-mail us and tell us we suck! We are well aware, and it does not feel good.”

The rest of the post offers some insight into how pollsters arrive at the numbers they publish. Apparently the problem wasn’t that PPP got bad information, but that it overestimated the turnout among two categories of voters.

I reweighted the results from our final Pennsylvania poll to those figures for race and age, and the result of our poll was flipped- Hillary leading 49-46. Assume she pulled 60% of the undecideds and that gives her the 52-48 lead that the extrapolation from the original exit polls does.
