About this Poll

The Illinois Emerson College/Nexstar poll was conducted March 11-12, 2020. The sample for the Democratic Primary consisted of registered Democratic, Republican, and Independent very likely voters, n=567, with a Credibility Interval (CI) similar to a poll’s margin of error (MOE) of +/- 4.1 percentage points. The data sets were weighted by gender, age, ethnicity, education, and region. 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 an Interactive Voice Response (IVR) system of landlines (n=234) and an online panel provided by MTurk (n=333).
