The best and most responsible pollsters, whether Democratic, Republican, or nonpartisan, want nothing so much as reliable results. Today, with a response rate in the single digits, they defend their work by pointing out that the people who do answer the phone are the people who are most likely to vote. Bill McInturff, of Public Opinion Strategies, told me, “The people we have trouble getting are less likely to vote.” But the difficulty remains. Surveying only likely voters might make for a better election prediction, but it means that the reason for measuring public opinion, the entire justification for the endeavor, has been abandoned. Public-opinion polling isn’t enhancing political participation. Instead, it’s a form of disenfranchisement.
