David Prosser gained 7,582 votes in Waukesha County, after a major counting error of Brookfield results was detected, County Clerk Kathy Nickolaus announced in a stunning development this afternoon. 
 
 Nickolaus says the reason for the big change is that data transmitted from the City of Brookfield was imported but that she failed to save those results to the database. Brookfield cast 14,315 votes on April 5 -- 10,859 of those votes went to Prosser and 3,456 went to JoAnne Kloppenburg. 
 
 "The purpose of the canvass is to catch these kind of mistakes," Nickolaus said. She called it human error that is "common in this process." "I apologize," Nickolaus said. 
 
 Canvassers around the state were updating their totals Thursday, with Prosser and JoAnne Kloppenburg each making gains. 
 
 Those changes pale in comparison to the stunning development in Waukesha County, where Prosser's total increased by 11,008 and Kloppenburg's rose 3,426. 
 
 Waukesha County's board of canvassers just met in the county courthouse in Waukesha. It was earlier reported that Prosser picked up 200 votes in New Berlin after a clerical error was discovered, according to Pat Karcher, a member of the board of canvassers in Waukesha County. Karcher spoke during a break in the canvassers meeting. The error occurred in Ward 12, where a vote for Prosser was reported as 37 but the tape revealed 237 votes for Prosser. 
 
 Nickolaus also said today that both candidates lost some votes in Lisbon. 
 
 Catching the errors boosted the turnout in Waukesha County to 47% from the previously reported 42%.

 Waukesha County Clerk Kathy Nickolaus said Thursday that the votes weren't reported to The Associated Press on Tuesday due to "human error." 
 
 Before the announcement, it was assumed 68-year-old conservative Justice David Prosser's race against liberal assistant state attorney general JoAnne Kloppenburg was headed for a recount. 
 
 But Prosser's lead is likely to stand if the new numbers hold up through canvassing in all of Wisconsin's 72 counties. 
 
 Opponents of the union rights law had hoped a Kloppenburg victory would set the stage for the high court to strike it down.
– Scott Walker foes, hold off on that celebration in Wisconsin. In a stunning turn of events that will no doubt leave Republicans gleeful and Democrats seething, GOP-backed David Prosser now looks like he's going to keep his seat on the state Supreme Court. Yesterday, his liberal-backed opponent, JoAnne Kloppenburg, declared victory when AP said she had a slim lead of about 200 votes. Today, a county corrected its total—and the new count gives Prosser a seemingly insurmountable 7,500-vote lead, reports AP. "The purpose of the canvass is to catch these kind of mistakes," said Waukesha County Clerk Kathy Nickolaus, who explained that results from one city failed to get saved into the database. She chalked it up to human error and added, "I apologize," notes the Milwaukee Journal Sentinel. The race turned into a proxy fight over Walker's law to curb union power, and opponents hoped a Kloppenburg victory would not only send a message to Republicans but also help overturn the measure on the state's high court.
