45-43 Pryor/Cotton
Technical note: This memo is based on a survey of 700 likely general election voters in Arkansas. Telephone interviewing was conducted August 26th through September 3rd, 2014. The sample was selected so all voters with a working telephone were equally likely to be contacted, and included both landline and cell phone numbers. The results were adjusted slightly to align the sample with known facts about the demographic composition of the off-year Arkansas electorate. All polls are subject to errors associated with interviewing a sample rather than the entire universe. The estimation associated with a sample of 700 is +/-3.7 percentage points.
