Report: Wisconsin Legislature maps have the worst partisan-bias of any court-drawn map in the nation

Noted: The new maps, drawn by the Wisconsin State Legislature, are considered the most partisan-biased, court-adopted maps in the nation. That’s according to a new analysis from the University of Wisconsin Law School. The maps heavily advantage Republican politicians, all but guaranteeing Republican-rule in the state Legislature, regardless of what most voters want.

The analysis looked at four metrics: partisan-bias, efficiency gap, mean-median difference and declination.

“On every one of these standard partisan fairness metrics, these new maps are the worst, court-adopted maps that we’ve seen anywhere in the country,” says Rob Yablon, an associate professor at the law school, who published the analysis.
