Conducted: October 21 - October 23, 2008
Completions: 430 total respondents; 417 likey voters
Modes used: telephone
Weights: votewgt
The sample of telephone exchanges called was randomly selected by a computer from a list of active residential exchanges within the State of Minnesota. Within each exchange, random digits were added to form a complete telephone number, thus permitting access to both listed and unlisted numbers. The sample was designed to represent different regions of the state in proportion to the number of adults living in each region. Within each household, one adult was selected to be the respondent for the survey.
Results are based on a model which adjusts responses according to the likelihood of a respondent voting. Likelihood to vote is based on the following factors: self-reported probability of voting in the upcoming election, voting in previous elections as reported by the respondent, enthusiasm for the 2008 election, and incorporates differential turnout levels in urban, suburban, and rural areas.
The results have been weighted to reflect different probabilities of selection based on the number of adults in a household and the number of telephone lines reaching the household. Results were also weighted to reflect the demographic characteristics of Minnesota based on region, sex, age, education, and race.
