Incumbent Republican Bill Huizenga and Democratic state Senator Sean McCann remain closely matched in Michigan's 4th congressional district ahead of the November 3 general election. The R+3 district, which supported the Republican presidential nominee by double digits in 2024, features recent polling averages showing a virtual tie or narrow margins within a few points, including a September survey placing McCann ahead by one point. Primary outcomes in August narrowed the field to these two major-party candidates, while ratings from outlets such as the Cook Political Report and Inside Elections classify the seat as Lean Republican, with some forecasters viewing it as a toss-up. Trader consensus around even odds and low-single-digit victory margins reflects uncertainty over turnout, independent voter preferences, and any late-cycle national or local developments that could shift the balance in this competitive battleground.
