About the poll

This Star Tribune/MPR News Minnesota Poll findings are based on interviews conducted Oct. 15-17 with 800 Minnesota likely voters. The interviews were conducted via land line (60 percent) and cellphone (40 percent). The poll was conducted for the Star Tribune and Minnesota Public Radio News by Mason-Dixon Polling and Research Inc.
Results of a poll based on 800 interviews will vary by no more than 3.5 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, and age groups.
The self-identified party affiliation of the respondents is 38 percent Democrats, 33 percent Republicans and 29 percent independents or other.
Sampling error does not take into account other sources of variation inherent in public opinion surveys, such as nonresponse, question wording or context effects. In addition, news events may have affected opinions during the period the poll was taken.
