WTMJ anchor John Mercure is reporting that election officials in the Republican stronghold of Waukesha County -- a Milwaukee suburb -- didn't count 14,000 ballots cast on Election Day. Those ballots will net Republican-backed judge David Prosser 7,381 votes, according to reporting from National Review.
National Review's Christian Schneider adds that county officials neglected to report data from the city of Brookfield, which accounted for those missing votes. If that margin holds, it could push Prosser's lead over union-backed candidate JoAnne Kloppenburg beyond the point where there would be an automatic recount.
Waukesha County voted overwhelmingly for Prosser on Election Night, giving him 73.5 percent of the original tally. It backed Gov. Scott Walker in last year's gubernatorial race with 72 percent of the vote.
A county elections official told Hotline On Call they will be holding a press conference at 6:30 EST to discuss the findings.
UPDATE, 6:13 p.m: The Milwaukee Journal-Sentinel is now reporting that Prosser picked up a net of 7,582 votes.
