Milwaukee County Circuit Judge Janet Protasiewicz defeated former Justice Dan Kelly, who previously worked for Republicans and had support from the state’s leading antiabortion groups. It’s his second loss in a race for a Supreme Court seat in three years.

The new court that will be controlled 4 to 3 by liberals is expected to decide a pending lawsuit challenging the state’s 1849 law banning abortion. Protasiewicz made the issue a focus of her campaign and won the support of Planned Parenthood and other abortion rights groups.

The court is also expected to hear a new challenge to Republican-drawn legislative maps. Protasiewicz ran as a critic of the current maps, calling them “rigged.”

The court came within one vote of overturning President Biden’s win in the state in 2020, and both major parties are preparing for another close race in 2024.

With so much at stake, the race became the most expensive contest for a state Supreme Court seat in U.S. history. Protasiewicz will begin her 10-year term in August. She replaces retiring conservative Justice Pat Roggensack.
