Illinois's 13th congressional district

Following the 2020 census and the subsequent redistricting cycle, the 13th congressional district was significantly altered to include Champaign, Urbana, most of Decatur and Springfield, and most of the Metro East of St. Louis.^[3] All of Macoupin County, and sections of Champaign, Macon, Madison, Piatt, Sangamon, and St. Clair Counties, are included in the new 13th.^[4] The redistricting turned the 13th district from a fairly even district to a more heavily Democratic-leaning one, and consequently, it elected a Democratic representative for the first time since 1892.
