The survey was carried out November 1-6, 2017 online from a nationally representative sample of Nielsen Scarborough’s probability-based panel, originally recruited by mail and telephone using a random sample of adults provided by Survey Sampling International. The national sample was 2,000, including a down-weighted oversample of 1,042 among 18-34 year olds. Responses were weighted by age, gender, income, education, race, and geographic region using benchmarks from the US Census. The survey was also weighted by partisan identification. The margin of error is 2.19%
