About this Poll
This survey of 1,032 adults was conducted July 15th through July 19th, 2018 by The Marist Poll sponsored and funded in partnership with NBC News. Adults 18 years of age and older residing in the state of Minnesota were contacted on landline or mobile numbers and interviewed in English by telephone using live interviewers. Mobile telephone numbers were randomly selected based upon a list of telephone exchanges from throughout the state of Minnesota from Survey Sampling International. The exchanges were selected to ensure that each region was represented in proportion to its population. Mobile phones are treated as individual devices. After validation of age, personal ownership, and non-business-use of the mobile phone, interviews are typically conducted with the person answering the phone. To increase coverage, this mobile sample was supplemented by respondents reached through random dialing of landline phone numbers from Survey Sampling International. Within each landline household, a single respondent is selected through a random selection process to increase the representativeness of traditionally under- covered survey populations. Assistance was provided by Luce Research for data collection. The samples were then combined and balanced to reflect the 2016 American Community Survey 5-year estimates for age, gender, income, race, and region. Results are statistically significant within ±3.7 percentage points. There are 876 registered voters. The results for this subset are statistically significant within ±4.0 percentage points. There are 340 voters in the potential Republican primary electorate. The potential Republican primary electorate in Minnesota includes all voters who prefer to vote in the August Republican primary and those who identify as Republicans or Republican leaning independents without a primary preference. There are 439 voters in the potential Democratic-Farmer-Labor primary electorate. The potential Democratic-Farmer-Labor primary electorate in Minnesota includes all voters who prefer to vote in the August Democratic-Farmer-Labor primary and those who identify as Democrats or Democratic leaning independents without a primary preference. The results for these subsets are statistically significant within ±6.4 percentage points and ±5.6 percentage points, respectively. The error margin was adjusted for sample weights and increases for cross-tabulations.
