About this Poll
The Emerson College poll for Iowa was conducted November 1-3 under the Supervision of Professor Spencer Kimball. The sample consisted of only likely general election voters, n=700, with a margin of error (MOE) of +/- 3.6 percentage points. The Iowa data was weighted by 2012 election results, party affiliation, age, and district. It is important to remember that subsets based on gender, age and party breakdowns 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 only.
