Regarding the Emerson poll:
The National Emerson College poll was conducted November 17-20, 2019 under the Supervision of Assistant Professor Spencer Kimball. The sample consisted of registered voters, n=1,092, with a Credibility Interval (CI) similar to a poll’s margin of error (MOE) of +/- 2.9 percentage points. The data was weighted based on 2016 voter model of age, mode, party registration, ethnicity, 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 both an Interactive Voice Response (IVR) system of landlines only (n=713) and an online panel provided by Amazon Turk (n=379).
