About this Poll
The Monmouth University Poll was sponsored and conducted by the Monmouth University Polling Institute from March 3 to 6, 2016 with a statewide random sample of Michigan voters drawn from a list of registered voters, who participated in a primary election in 2012 or 2014 or voted in both of the last two general elections, and indicate they will vote in the presidential primary on March 8, 2016. Monmouth is responsible for all aspects of the survey design, data weighting and analysis. Final sample is weighted for age and gender based on state registration list information on the pool of voters who participate in primary elections. Data collection support provided by Braun Research (field) and Aristotle (voter list). The total sample of 704 likely voters includes 444 contacted by a live interviewer on a landline telephone and 260 contacted by a live interviewer on a cell phone, in English.

For results based on the sample of 302 likely Democratic primary voters, one can say with 95% confidence that the error attributable to sampling has a maximum margin of plus or minus 5.6 percentage points (unadjusted for sample design). Sampling error can be larger for sub-groups (see table below). In addition to sampling error, one should bear in mind that question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of opinion polls.
