Wisconsin Gov. Scott Walker (R) was projected the winner of Tuesday night's gubernatorial primary by NBC News.
The latest polls showed Walker leading Democratic challenger Milwaukee Mayor Tom Barrett going into the contest.
The AP relays background on the race:
The first-term Republican was back on the ballot just a year and a half after his election. Enraged Democrats and labor activists gathered more than 900,000 signatures to force the vote after they failed to stop Walker and his GOP allies in the state Legislature from stripping most public employees of their collective bargaining rights.
The recall is a rematch of the 2010 election in which Walker beat Democratic Milwaukee Mayor Tom Barrett by nearly 6 points.
