MADISON, Wis. (AP) — The battle for a nonpartisan seat on the Wisconsin Supreme Court is a partisan-driven slugfest seen as a possible harbinger of voter attitudes heading into the fall midterms. Sensing that a victory in Tuesday’s election could be a momentum-builder, a bevy of national Democrats has endorsed Rebecca Dallet, a Milwaukee County judge. She’s running against Michael Screnock, a judge appointed by Republican Gov. Scott Walker. A group run by former U.S. Attorney General Eric Holder, who served under Democratic President Barack Obama, has spent $165,000 on digital ads for Dallet. The state Republican Party is spending about $400,000 to help Screnock. The race is the first statewide contest in the U.S. this year. It comes after a Democrat won a surprising victory in a special Wisconsin state Senate election in January.
