Liberal Rebecca Dallet has easily defeated conservative Michael Screnock in a Wisconsin Supreme Court race seen as the latest bellwether of voter attitudes ahead of the November election.
Dallet's victory cuts conservative control of the state's highest court from 5-2 to 4-3. She also becomes the sixth woman on the seven-member court.
Conservative Justice Michael Gableman did not seek a second 10-year term.
Wisconsin's high court has become notably partisan in recent years even though it's nonpartisan in name.
Dallet, a Milwaukee County judge, drew strong Democratic support including an endorsement from former Vice President Joe Biden.
Screnock, a Sauk County judge appointed and endorsed by Republican Gov. Scott Walker, had the backing of the National Rifle Association and the Wisconsin Republican Party.
