The current district is fairly conservative. Huron, Lapeer, St. Clair, and Sanilac counties tend to support Republican candidates, as do the northern townships in Macomb and the eastern townships in Tuscola. With 15.5%, this district has the largest proportion of Polish Americans in the country. The district is currently represented by Lisa McClain, who was first elected in 2020.
From 1992 to 2002 the 10th congressional district included St. Clair County, and slightly more than half of Macomb Counties population, but lacking the cities of Sterling Heights, Michigan and Warren, Michigan. In the 2002 redistricting Lapeer County, Huron County, Sanilac County and about two thirds of Sterling Heights were added to the district. At the same time Clinton Township, Mt. Clemens, St. Clair Shores, Fraser and Roseville were removed from the district.
Prior to the 1992 redistricting the 10th district had its largest city as Midland and roughly corresponded to the present 4th district. The post-1992 10th district was very similar to the previous 12th district, although it took small areas from the 18th district, the 14th district and the 8th district, and lost north-west Warren to the new 12th district.
