More on Pre-Election Polling

Mark Blumenthal at The Huffington Post has written again about Gallup’s methodological work in our 2012 pre-election polling — albeit rather belatedly from our original announcements about our review plans in late January. …

Mark has written a number of posts about Gallup now, but we haven’t seen a lot from him about other pollsters whose final election estimates were similar to Gallup’s. We would hope to see Mark make a similar investment of effort looking at the broader pattern of pollsters’ under-representing support for Obama in 2012 — something that NCCP and others have documented. We are all dealing with very complex sampling, weighting, and measurement issues that involve levels of judgment, as well as a scientific basis for how they are executed. [cont.]
