Sauk County Judge Michael Screnock is seen as the lone conservative in the Supreme Court race.
He is battling Madison lawyer Tim Burns and Milwaukee County Judge Rebecca Dallet in next week's nonpartisan primary.
"Screnock says his two opponents - Tim Burns and Rebecca Dallet - have criticized laws signed by Governor (Scott) Walker and have campaigned as activists who will legislate from the bench," said Tom Kertscher with the Milwaukee Journal Sentinel.
Burns and Dallet have been appealing to Democrats and progressive voters.
PolitiFact Wisconsin says Burns has made no secret of his dislike for Walker.
"Burns has criticized a number of laws signed by the governor including Act 10 which curbed union powers," said Kertscher.
PolitiFact Wisconsin says Dallet has been vocal about her values but...
"Dallet does not criticize laws directly that were signed by Gov. Walker," said Kertscher, "although she did criticize the Supreme Court for the way it did its legal analysis of act."
PolitiFact Wisconsin points out Judge Screnock was appointed to the bench by Governor Talker. His claim was rated Half True, meaning it is partially accurate.
