Seriously? You want to make an ad hominem argument against a critique of a poll when the poll was carried out by an outfit called the Public Religion Research Institute ? with a product called the American Values Atlas?
Your first question: “ Can you explain how it’s possible that The Hill would have knowledge of the poll respondents’ demographics a year prior to the data sets being made public?”
Answer: Easy. He read this: “ The 2016 American Values Atlas (AVA) is a project of PRRI. Results for all questions were based on weekly bilingual telephone interviews of 40,509 adults (including roughly 60 percent who were interviewed by cell phone) conducted between May 18, 2016 and January 10, 2017 by professional interviewers under the direction of SSRS. The AVA was made possible by generous grants from The Ford Foundation, The Carnegie Corporation of New York, the Arcus Foundation, the Gill Foundation, and the Nathan Cummings Foundation… . The selection of respondents within households was accomplished by randomly requesting to speak with the youngest adult male or female currently living in the household.” https://www.prri.org/wp-content/uploads/2017/01/PRRI-AVA-Topline-Trends-2016-FINAL.pdf
While Rep. Smith is laughably uninformed about climate science, he accurately noted the problems with this poll. He is accurate as to the funding of the poll. And he notes, correctly, that the Washington Post, which surveyed registered voters, differs significantly from the PRRI poll of random adults.
Generally, I am skeptical of polls which produce results so in line with the funders’ viewpoints.
