The surveys show Biden narrowly ahead of Trump among likely voters in Michigan by 51 percent to 44 percent, with Libertarian Party nominee Jo Jorgensen at 3 percent. In Wisconsin, likely voters favor Biden by 57 percent to 40 percent, with Jorgensen at 2 percent. Among registered voters, Biden’s edge in Michigan is five points, while he leads by 17 points in Wisconsin.

Biden’s margins in both states are driven by overwhelming support among female likely voters. He leads Trump by 24 points among those women in Michigan and by 30 points in Wisconsin. Biden trails Trump among Michigan men by double digits, and the two are running about even among men in Wisconsin.

The findings suggest concerns about the coronavirus are weighing heavily on Trump’s candidacy, particularly in Wisconsin, which has seen case counts climb to record levels in recent weeks. When it comes to handling the pandemic, Biden is trusted more than Trump by double digits in both states, and large majorities support their state’s rules on masks and restrictions on businesses and public gatherings.
