According to this story, the Wisconsin Democratic Party has filed a challenge to the primary ballot access of Tim Michels, a leading Republican candidate for Wisconsin Governor. Candidates for statewide office in Wisconsin need 2,000 signatures to get on a primary ballot. The challenge says he didn’t list his address properly.
A similar problem kept the Green Party off the presidential ballot in Wisconsin in 2020.
The 2022 Wisconsin primaries are in August. Three other Republicans are also running in the primary for Governor. Thanks to Michael Drucker for this news.
