Incumbent Republican Bill Huizenga seeks a ninth term in Michigan’s 4th Congressional District against Democratic state Senator Sean McCann in the November 3 general election. The race remains tight because the district, which Trump carried by roughly six points in 2024, features shifting voter trends and has drawn national focus as one of roughly two dozen contests that could decide House majority control. McCann has secured major labor endorsements and strong third-quarter fundraising, while recent polling shows the candidates separated by only a few points. Speaker Mike Johnson’s October 7-8 campaign visit for Huizenga underscored Republican efforts to hold the seat amid voter concerns over energy costs, utility rates, and plant operations. Trader consensus at 52.5 percent for Huizenga reflects these fundamentals, with potential separation hinging on turnout in key counties, late-cycle messaging on affordability, and any shifts in national conditions before Election Day.
