MADISON, Wis. (AP) — About 20% of the state’s voting-age population cast ballots in the Wisconsin Supreme Court primary, state elections officials said Thursday.

The Wisconsin Elections Commissions announced Wednesday that unofficial results show voters cast at least 960,477 ballots in Tuesday’s primary. That translates to 20.5% of the 2022 voting age population of 4,676,183 people as counted by the state Department of Administration.

The turnout was among the highest for a spring primary election with a state Supreme Court contest in recent years.

Milwaukee County Circuit Judge Janet Protasiewicz and ex-Justice Dan Kelly were the top two vote-getters in a four-candidate field and advanced to the April 4 general election. Protasiewicz won with about 46% of the vote, while Kelly came in second with about 24%.
