About this Poll

The survey of 800 likely Michigan voters was conducted by live interview July 11-15, 2016. The sample was randomly drawn from a listed sample of all registered voters with a history of voting and stratified by city and township to reflect voter turnout.

In addition, quotas for gender and cell phone interviews were met within each geographic area, and extra efforts were made to reach African Americans. Thirty percent of the interviews were conducted with cell phone only or cell phone dominant households.

A sample of 800 likely voters in Michigan yields a sampling margin of error of ±3.46 percent with a 95 percent confidence interval.
