Protasiewicz along with Dane County Circuit Judge Everett Mitchell are running as liberal candidates in the race. Waukesha County Circuit Judge Jennifer Dorow and former Wisconsin Supreme Court Justice Dan Kelly are the conservative candidates.
The top two vote-getters in the Feb. 21 primary will advance to the April 4 election. The winner replaces conservative Justice Patience Roggensack, who is retiring.
Races for the Wisconsin Supreme Court are officially nonpartisan, but candidates for years have aligned with either conservatives or liberals as the contests have become expensive partisan battles. The conservative-controlled court for more than a decade has issued consequential rulings in favor of Republicans, with major cases looming that could determine the future of abortion laws, redistricting and rules of elections.
The candidates and outside interests that have promised to spend millions on the race have been relatively quiet up to this point, more than a month before the primary. But those on both sides have made clear they see the race as crucial in the battleground state, with whoever winning determining ideological control of the court heading into the 2024 presidential race and at least a year after.
