The Wisconsin race for governor has no clear leader, while Democratic gubernatorial candidates hold the edge in Michigan and Pennsylvania, according to new CNN polls conducted by SSRS in the three key states.

Wisconsin’s incumbent Democratic Gov. Tony Evers has the support of 50% of likely voters, while Republican Tim Michels has 48%, a finding that’s well within the survey’s margin of error.

In Michigan, incumbent Democratic Gov. Gretchen Whitmer leads Republican Tudor Dixon among likely voters, 52% to 46%. Voters are 6 percentage points likelier to view Whitmer favorably than unfavorably, while Dixon’s rating is underwater by 10 points.
