How the poll was conducted

The Star Tribune Minnesota Poll findings are based on telephone interviews conducted Sept. 10-12 with a representative sample of 1,201 Minnesota adults, 18 years old and over. For questions concerning politics, the results are based on the 1,106 respondents designated as likely voters based on their voting intentions and self-reported voting history.

Interviews were conducted under the direction of Princeton Survey Research Associates International. Results of a poll based on 1,201 interviews will vary by no more than 3.8 percentage points, plus or minus, from the overall population 95 times out of 100. Margins are larger for groups within the sample, such as Democrats and Republicans.
