Michigan’s 6th Congressional District covers much of southeastern Michigan, anchored by Ann Arbor and Washtenaw County and extending into parts of Wayne, Oakland, and Monroe counties. It is represented by Democrat Debbie Dingell and has been a reliably Democratic seat since taking its current shape for the 2022 election.
Where the District Is
The core of the district is all of Washtenaw County, home to Ann Arbor and the University of Michigan.1U.S. Census Bureau.

The Wayne County portion covers much of the county’s western and southern areas, including Canton Township, Plymouth, Northville, Van Buren Township, and downriver communities such as Trenton, Woodhaven, Riverview, Grosse Ile Township, and Brownstown Township.2Congresswoman Debbie Dingell. 6th District In Oakland County, the district takes in Commerce Township, Lyon Township, Milford, Highland Township, White Lake Township, Waterford Township, West Bloomfield Township, Novi, and parts of Bloomfield and Southfield.1U.S. Census Bureau.

Who Represents the District
Debbie Dingell has held the seat since the current map took effect, having moved over from the old 12th District for the 118th Congress in 2023. She has served in the U.S. House since 2015 and was sworn in for her sixth term in January 2025.3Congress.gov. Debbie Dingell Member Page
In the 119th Congress, Dingell sits on two committees. On Energy and Commerce, she serves on the subcommittees for Health; Communications and Technology; and Commerce, Manufacturing, and Trade. On Natural Resources, she serves on the subcommittees for Energy and Mineral Resources and Water, Wildlife and Fisheries.4Clerk of the U.S. House of Representatives.

How the District Votes
The 6th is one of the safest Democratic seats in Michigan. Retroactive analysis of the 2020 presidential vote under the current lines shows the Democratic candidate would have carried the district roughly 63% to 36%. The Ann Arbor core is dominated by university employees, students, healthcare workers, and research institutions, and the suburban Oakland and Wayne County communities added in redistricting lean Democratic as well.
Actual results have matched that lean. In 2022, the first cycle under the new map, Dingell won with about 66% of the vote. In 2024 she won again, taking 62.0% to Republican Heather Smiley’s 35.0%, with third-party candidates splitting the remainder. Consistent margins at that level mean the competitive race in this district is the Democratic primary rather than the general election. The population is majority White, with significant Asian, Black, and Hispanic communities.
Why the District Looks This Way Now
After the 2020 Census, Michigan lost a seat and dropped from 14 to 13 congressional districts.5United States Census Bureau.

One practical consequence matters for anyone looking up older results. The old 6th District sat in the southwestern corner of the state around Kalamazoo and St. Joseph and was a generally Republican-leaning seat; the current 6th is hundreds of miles away in the Ann Arbor area and shares no meaningful territory or political character with it. Only election results from 2022 onward reflect the district as it exists today.
