Wisconsin 2022 - 2024 Districts

Overview of 2020 Redistricting

Wisconsin’s congressional districts are drawn through the ordinary legislative process: a bill passes both chambers and goes to the governor, with no super-majority or commission backstop. Because the state often has divided government, impasses send the job to the courts. After Gov. Tony Evers vetoed the GOP legislature’s 2021 proposal, the Wisconsin Supreme Court embraced a “least-change” approach and, in Johnson v. Wisconsin Elections Commission, formally adopted the governor’s map on March 3, 2022; the U.S. Supreme Court left that plan untouched. The eight-seat map, therefore, remains the law, and in June 2025, the state high court summarily dismissed two new lawsuits seeking a map overhaul before the 2026 election.

The state-legislative lines follow the same statute-and-veto path, but Article IV of the Wisconsin Constitution layers on stricter rules: every district must be contiguous, “as compact as practicable,” honor local boundaries where possible, and each of the 33 Senate districts must have three of the 99 Assembly seats nested within them. After the court’s initial 2022 “least-change” map was reversed by the U.S. Supreme Court, the justices installed the legislature’s version for that year’s elections. A newly configured 4-3 liberal majority reopened the matter in Clarke v. WEC, ruling on December 22, 2023, that the plan’s island-like districts violated the Constitution’s contiguity clause. Facing a tight deadline, lawmakers in February 2024 passed Governor Evers’ remedial map proposal intact.
