Democrat Sean McCann defeated eight-term Republican Rep. Bill Huizenga in Michigan’s 4th Congressional District, leading 50.1% to 48.3% with more than 97% of votes counted when the Associated Press called the race on Nov. 4, 2026.

McCann’s win was at least the third Michigan congressional seat to flip to Democrats, following William Lawrence’s victory in the 7th District and Christina Hines’ win in the 10th District.

The result was a major upset in a district rated Lean Republican, where McCann’s lead was about 7,000 votes.

McCann has served in the Michigan State Senate since 2018 and previously represented the area in the State House from 2011 to 2015; Huizenga has served in Congress since 2011.

McCann said he had represented the greater Kalamazoo area in some capacity for 22 years and that attending Western Michigan University first brought him to the community.

In his victory speech, McCann said his campaign traveled throughout the district to hear voters’ concerns and criticized Huizenga for not holding a town hall since 2018.

McCann thanked voters, volunteers, supporters and Huizenga for his years of service, and said he would work to address corruption and policies he believes shortchange families while improving life for Southwest Michigan residents.

McCann said his campaign focused on ending wars and suffering, improving prosperity, and promoting community health and well-being.

He credited former U.S. Senator Carl Levin and former Congressman Howard Wolpe as influences on his public-service career.

Fairshake, a crypto-industry super PAC, reported spending $1,019,166 to support Huizenga, who was vice chair of the House Financial Services Committee and served on its digital assets subcommittee.

Outside groups spent more than $25 million in the district, including about $6 million from House Majority PAC to oppose Huizenga, making Fairshake’s contribution a small share of the overall spending.

Huizenga’s defeat, alongside Bryan Steil’s loss, removes two Republicans who helped shape crypto legislation on the committee; Huizenga had helped advance the stablecoin bill signed by President Donald Trump in 2025 and led committee investigations into former SEC Chair Gary Gensler.
