All voters in Wisconsin will participate in the primary, since three candidates are running in a statewide race for superintendent of public instruction. Two will advance to the April 1 general election.

You might have also heard about a state Supreme Court race this spring. Only two candidates are running, meaning there's no primary for that race.

Depending on where you live, you may have a primary for other local, nonpartisan races on your ballot, like circuit court judges, city council members or school board members.
