Cell-phone and home-phone respondents included in this research. SurveyUSA interviewed 700 registered voters from Minnesota's 8th Congressional District 10/07/12 through 10/09/12, using registration-based (voter-list) sample from Aristotle in Washington DC. Of the registered voters, SurveyUSA determined that 578 were likely to vote in the 11/06/12 election. This research was conducted 100% by telephone. Respondents reachable on a home telephone were interviewed on their home telephone in the recorded voice of a professional announcer. Respondents not reachable on a home telephone were called on their cell phones, by live operators who hand-dialed the phone, qualified the respondent, secured the respondent's cooperation, asked the questions and remained on the line until the conclusion of the interview.
