HOW THE POLL WAS CONDUCTED
Tuesday's Star Tribune Minnesota Poll findings were based on 526 land-line and 281 cellphone interviews conducted Nov. 2-3 with a representative sample of Minnesota adults.
Interviews were conducted under the direction of Princeton Survey Research Associates International.
Results of a poll based on 807 interviews will vary by no more than 4.4 percentage points, plus or minus, from the overall population 95 times out of 100.
The self-identified party affiliation of the random sample is 34 percent Democrat, 24 percent Republican and 33 percent independent. The remaining 9 percent said they were members of another party, no party or declined to answer.
Sampling error does not take into account other sources of variation inherent in public opinion surveys, such as non-response, question wording, context effects or news events.
