I'll take that as more indicative of trend lines than the current spate of polls. Especially in light of this information. WE ARE THE 91%: Only 9% of Americans Cooperate with Pollsters
It has become increasingly difficult to contact potential respondents and to persuade them to participate. The percentage of households in a sample that are successfully interviewed – the response rate – has fallen dramatically. At Pew Research, the response rate of a typical telephone survey was 36% in 1997 and is just 9% today.
All those poll results are just percentages of 9% of people who will talk to pollsters. No wonder they seem oddly out of wack.
