UPDATE: Aug. 13 -- The Associated Press has redacted results for Wisconsin's 6th District primary. With 100 percent of precincts reporting, the margin of victory has proved too close to call in the contest between Glenn Grothman and Joe Leibham.
As reported previously, the Associated Press called the race in favor of Grothman, who held a strong lead before all votes were tallied. But with 100 percent of precincts reporting, Grothman only holds 214 votes more than Leibham, prompting the Associated Press to "uncall" the race.
All counties in the congressional district will have to certify their results, and the Government Accountability Board will have to approve those results before either of the candidates can request a recount, according to Fond du Lac County Clerk Lisa Freiberg.
State Sen. Glenn Grothman has won the Republican nomination in the race to represent Wisconsin's 6th District in the U.S. House of Representatives, the Associated Press reports.
Rep. Tom Petri (R-Wis.) announced in April his decision to retire at the end of the congressional term, opening up the race.
Grothman will face Mark Harris in the November general election. Harris ran unopposed in the Democratic primary.
The Huffington Post's Amanda Terkel and Samantha Lachman reported earlier on the primary race:
Four Republicans are vying to replace retiring Rep. Tom Petri (R) in the most high-profile race in the state Tuesday. The man with the biggest target on his back is state Sen. Glenn Grothman (R), who has made a name for himself championing conservative causes. He sponsored legislation that repealed the state's Equal Pay Enforcement Act, fought for a seven-day workweek and proposed a bill that would have considered single parenthood "a contributing factor to child abuse and neglect." State Sen. Joe Leibham (R) and state Rep. Duey Stroebel (R) also describe themselves as conservatives, although Leibham has stressed his ability to build consensus and Stroebel has talked up his business background. The fourth candidate in the primary race, Tom Denow, is a political newcomer and is considered the dark horse candidate. The winner of the GOP primary will face Winnebago County Executive Mark Harris (D). The district leans Republican.
