Two democrats and three republicans are hoping to fill the congressional seat soon to be vacated by Paul Mitchell. It will be a heated primary in August as republicans Shane Hernandez, Lisa McClain, and Doug Slocum vie for their party’s nomination. On the democratic side, Kimberly Bizon and Kelly Noland will attempt to flip the traditionally red 10th district to blue. They’ll square off in the August fourth primary, with the winner from each party moving on to the November ballot. The tenth congressional district includes all of the Thumb including St. Clair, Sanilac, Lapeer, Huron, and Tuscola counties as well as portions of Northern Macomb. Mitchell last summer announced that, after two terms in office, he will not be seeking re-election.
