Incumbent Republican Bill Huizenga and Democratic state Senator Sean McCann remain locked in a tight contest for Michigan’s 4th congressional district, with recent polling averages showing margins under 3 points and forecasters rating the seat a toss-up or lean Republican. The September GBAO survey found McCann ahead by 1 point among likely voters, reflecting strong Democratic performance among independents and mixed views of the national environment. Huizenga’s incumbency and primary strength provide a base, while McCann’s fundraising and primary win position him to contest the district’s suburban and independent voters. Limited recent movement in surveys and the November 3 general election timeline leave room for shifts from turnout, late advertising, or broader partisan trends to determine the final margin.
