Redistricting
In Wisconsin, both congressional and state legislative district boundaries are drawn by the Wisconsin State Legislature. These lines are subject to veto by the governor.[11]
The Wisconsin Constitution requires that state legislative districts be compact and "that they be bounded by county, precinct, town, or ward lines where possible." The state constitution further stipulates that state legislative districts should be contiguous.[11]
On February 19, 2024, Gov. Tony Evers (D) signed Senate Bill 488 into law, adopting new Wisconsin legislative maps.[12] The maps were approved by majority votes in both chambers of Wisconsin's state legislature on February 13. The state Senate voted 18-14 in favor of adopting the new legislative maps, while the state Assembly vote total was 63-33.
In the 2023 Wisconsin Supreme Court election, Janet Protasiewicz had defeated Daniel Kelly, changing the balance of the court from a conservative to a liberal majority for the first time in 15 years.[13][14] Later that year on December 22, 2023, the Wisconsin Supreme Court ruled in a 4-3 vote that the state's legislative maps were unconstitutional and ordered new maps to be drawn before the 2024 election.[15] The court rejected the least change approach the conservative majority had adopted for the 2022 maps and ruled that the new maps must satisfy the state constitution's contiguity requirements.[16]
Senate elections
Wisconsin state senators serve staggered, four-year terms and half of the state Senate is up for election every two years. Wisconsin holds elections for its legislature in even years.
