About this Poll
The Iowa Emerson College poll was conducted December 7-10, 2019. The sample consisted of registered voters, n=1,043, with a Credibility Interval (CI) similar to a poll’s margin of error (MOE) of +/- 3 percentage points. The data was weighted based on 2016 voter model of congressional district, gender, age, education, party affiliation. It is important to remember that subsets based on gender, age, party breakdown, ethnicity and region carry with them higher margins of error, as the sample size is reduced. Data was collected using both an Interactive Voice Response (IVR) system of landlines only (n=684) and an online panel provided by Dynata and MTurk (n=359).
