About this Poll
This survey of 943 adults was conducted September 30th through October 3rd, 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 Wisconsin 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 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 The Logit Group 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 781 registered voters. The results for this subset are statistically significant within ±4.1 percentage points. There are 571 likely voters defined by a probability turnout model which determines the likelihood respondents will participate in the November 2018 election based upon their chance of vote, interest in the election, and past election participation. The results for this subset are statistically significant within ±4.8 percentage points. The error margin was adjusted for sample weights and increases for cross-tabulations.
