55.4 Supreme Court Election Results
Wisconsin’s Supreme Court has 7 justices, each of whom are elected to 10 year terms in statewide elections held in April. State law prohibits more than one Supreme Court election from being held in a single year. If a seat becomes vacant, the governor appoints a replacement who serves until the next year in which no court election is already scheduled. If more than two candidates achieve ballot access, a nonpartisan, top-two primary is held in February.
Court elections are formally nonpartisan, but candidates are usually supported by either liberals or conservatives. In recent years, it has become common for the Democratic and Republican parties to endorse and actively campaign on behalf of favored judicial candidates. The liberal and conservative labels indicated in the following graphs and tables are based on widely recognized tendencies, not any formal affiliation.
