Ahead of the Democrats’ second presidential primary debate in Detroit, a new survey finds Michigan voters have deep concerns about the impacts of climate change and the quality of their state’s environment and infrastructure. Democratic voters in Michigan say climate change is one of the most important issues they’ll consider when deciding whom to support for president in 2020 – more than any other issue except health care. Voters in the state strongly support federal and state policies to expand renewable energy sources, including policies that would encourage people to buy and drive electric vehicles. To assess Michiganders’ attitudes towards various climate policies, as well as their experiences with impacts of climate change, Climate Nexus, in partnership with the Yale University Program on Climate Change Communication and the George Mason University Center for Climate Change Communication, conducted a representative survey of 820 registered voters in Michigan from July 14-17, 2019. The margin of error for this survey is +/- 3.4% at the 95% percent confidence level.
