Michigan's 4th congressional district race features incumbent Republican Bill Huizenga facing Democratic state Sen. Sean McCann in a contest now rated a toss-up by multiple forecasters. The district's partisan lean and recent polling averages near parity, with one late October survey showing Huizenga ahead by just over 3 points within the margin of error. McCann has benefited from strong fundraising in the final quarter, roughly even outside spending exceeding $15 million, and high-profile campaign appearances by Gov. Gretchen Whitmer and Sen. Elissa Slotkin. Voters are focusing on energy costs, data centers, and affordability. With the Nov. 3 election only days away, trader consensus in prediction markets reflects the race's competitiveness and late momentum shifts rather than historical margins.
