The latest in Wisconsin

Dec. 16, 2021

On Nov. 18, Gov. Tony Evers vetoed the congressional map passed by Republicans in the state legislature, sending responsibility for redistricting to the Wisconsin Supreme Court. On Nov. 30, the court announced that it would not consider partisanship when drawing new congressional and state legislative maps and would instead try to make as few changes as possible to the old maps.

The court’s decision makes it likely that the strong Republican bias in Wisconsin’s congressional map will survive another decade. The old map, which was drawn by Republicans in 2011, has an extremely high efficiency gap of R+27. However, Wisconsin’s political geography (Democrats are highly concentrated in Dane and Milwaukee counties, while Republicans aren’t as highly concentrated in any one part of the rest of the state) also makes it very difficult to put Democrats and Republicans on equal footing in the state without drawing funkier lines and breaking up municipalities.

This ruling doesn’t lock anything in, however. The court’s swing justice wrote that he is open to considering criteria other than minimizing the number of changes, and state law prescribes other criteria (like compactness and not splitting counties) that are actually at odds with the least-changes doctrine.

Since the ruling, both Republican lawmakers and Gov. Evers have submitted proposals to the state Supreme Court. Evers’s proposal would make even fewer changes to the current map than Republicans’ proposal, while also reducing the partisan bias of the maps. The deadline for submitting proposals to the court was Dec. 15, and arguments will be heard in mid-January.

Wisconsin Gov. Evers vetoed SB 622 (congressional districts) and SB 621 (legislative districts), calling them "gerrymandering 2.0." The Wisconsin Supreme Court previously agreed to draw new maps if the political process failed, and ordered parties to submit proposed maps by noon on Dec. 15, 2021. A federal court has stayed a challenge by Democrats until the state supreme court completes its process.
