One of the most notable partisan gerrymanders in the country can be found in Wisconsin. But a repeat of the offense in 2021 can be prevented – with public input.
Governor Evers has formed a nonpartisan citizen commission to increase transparency and collect public input, regardless of whether the legislature intends to bypass him or not.
