A conservative incumbent surged to a commanding lead in Wisconsin's hotly contested Supreme Court election [on April 7], after a predominantly GOP county's clerk announced she had incorrectly entered vote totals in the race seen as a referendum on Republican Gov. Scott Walker's divisive union rights law. Waukesha County Clerk Kathy Nickolaus said more than 14,000 votes weren't reported to The Associated Press on [April 5, election day] due to human error.'' Nickolaus previously worked for a GOP caucus that was under the control of Justice David Prosser, who was speaker of the Assembly at the time and who now stands to benefit from the clerk's error. Before the announcement, it was assumed 68-year-old conservative Prosser's race against liberal assistant state attorney general JoAnne Kloppenburg was headed for a recount. But Waukesha County's corrected totals gave Prosser a 7,500-vote lead, which is likely to stand. Opponents of the law that takes away nearly all public employee collective bargaining rights had hoped a Kloppenburg victory would set the stage for the high court to strike it down. Rep. Peter Barca, Democratic Assembly minority leader, said the mistake raises significant suspicion that could warrant an investigation. "It doesn't instill confidence in her competence or integrity,'' Barca said.
