Nationwide Voter Survey: Report on results
From Thursday, November 16 through Monday, November 20, 2017 J. Wallin Opinion Research conducted a telephone survey of voters nationwide. We interviewed 1,000 respondents using live, professional interviewers, speaking Spanish and English languages and calling both mobile and landlines (44% of this survey was completed on mobile phones). A survey of this size yields a margin of error of +/-3.1% (95% confidence interval). Our sample is stratified, meaning that the demographic composition of our results matches the demographic composition of the voters nationwide. J. Wallin Opinion Research performs research on behalf of business, government and political clients.
