The +4% Dem survey of 600 likely Michigan voters was conducted by live interview March 16-20. 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. Thirty percent of the sample was conducted with cell phone users. In addition, quotas for gender and cell phone interviews were met within each geographic area, and extra efforts were made to reach African Americans.

A sample of 600 likely voters in Michigan yields a sampling margin of error of ±4 percent with a 95 percent confidence interval. The sampling margin of error for subgroups may be higher depending on the size of the subgroup.
