Charlotte Observer: Election pollsters explain why they got it wrong on Kay Hagan-Thom Tillis

Pearce Godwin, director of Raleigh-based, conservative-leaning American Insights, said polling this year failed to predict the wave that swept Democrats out of office at all levels across the country.

“With survey response rates in the single digits and 41 percent of Americans now cellphone only, gaining a representative sample and accurate data on a population is an increasingly steep challenge for pollsters in all industries,” he said in an email.
