About this Poll
This survey of 1,772 adults was conducted July 7th through July 13th, 2014 by The Marist Poll sponsored in partnership with NBC News. Adults 18 years of age and older residing in the state of Iowa were interviewed by telephone using live interviewers. Landline telephone numbers were randomly selected based upon a list of telephone exchanges from throughout the state of Iowa from ASDE Survey Sampler, Inc. To increase coverage, this landline sample was supplemented by respondents reached through random dialing of cell phone numbers from Survey Sampling International. The two samples were then combined and balanced to reflect the 2010 Census results for age, gender, income, and race. Respondents in the household were selected by asking for the youngest male. Results are statistically significant within ±2.3 percentage points. There are 1,599 registered voters. The results for this subset are statistically significant within ±2.5 percentage points. The error margin increases for cross-tabulations.
