How to explain it I cannot say with certainty. Some evidence suggests that the pollsters poll a higher percentage of Democrats than Republicans. Moreover, a recent poll from the Pew Research Center is suggestive. The electorate is growing impatient with pollsters calling them for their views on everything from deodorants to odors. According to Pew, “the response rate of a typical telephone [political] survey was 36% in 1997 and is just 9% today.” My suspicion is that political polling has not been reliable for years. Increasingly those who sit down with the pollster are politically committed respondents.
