Under legal pressure to address Wisconsin’s “Swiss cheese” and oddly shaped districts, the Legislature approved redrawn maps that promise to create a new dynamic in a state known for its pivotal role in national politics.

Even under the governor’s maps, the GOP is still expected to retain majorities in both chambers, though the party’s advantage would likely be slimmer than the absolute authority it now commands, particularly in the Senate. Currently, the GOP has a supermajority in the Senate and a near supermajority in the Assembly.

Prior to the legislative action, justices had been set to select new district maps from a group of proposals, including the one from Evers. Indications were the decision would not be favorable to the GOP.

Rather than take their chances, Republicans decided to approve the governor’s maps, which are considered to be “friendlier” to the GOP than the others when measuring partisan bias and incumbent matchups.
