Incumbent Democrat Hillary Scholten faces Republican nominee Terri DeBoer in Michigan's 3rd congressional district, which covers western Michigan including Grand Rapids and Muskegon. Recent primary results confirmed both nominees in August 2026, with Scholten unopposed and DeBoer securing a strong GOP nomination. Nonpartisan race ratings classify the seat as likely or safe Democratic, consistent with the district's partisan lean and Scholten's prior performance. Traders price the most probable Democratic victory margins in the 15-25 point range, reflecting the seat's structural advantage for Democrats alongside potential shifts from national midterm dynamics, candidate spending, and voter turnout in suburban and rural counties. A Republican upset remains a low-probability outcome given historical patterns in the district.
