Cell-phone and home-phone respondents included in this research, which was conducted 100% by telephone. SurveyUSA interviewed 700 registered voters from Minnesota's 7th Congressional District 10/03/14 through 10/06/14, using Registration Based Sample (aka: voter-list sample) provided by Aristotle of Washington DC. Of the registered voters, 545 were determined by SurveyUSA to be likely to vote in the 11/04/14 general election. This research was conducted 100% by telephone. Voters reachable on a home telephone (83% of likely voters) were interviewed on their home telephone in the recorded voice of a professional announcer. Voters not reachable on a home telephone (17% of likely voters) were interviewed by live operators, who hand-dialed the telephone, secured the respondent's cooperation, qualified the respondent, conducted the interview, and remained on the line until the interview was concluded.
