Wisconsin Supreme Court Justice David Prosser was supposed to win reelection in a walk, after winning a February primary with 55% of the vote . Prosser, a former Republican state assemblyman, faced JoAnne Kloppenburg, who previously served as the state’s assistant attorney general and came in second in the primary. But Governor Scott Walker’s brazen push to bust unions and implement an ultraconservative political agenda spurred the progressive community into action, and Walker’s popularity plummeted .
Many of the Wisconsinites who are outraged over the right-wing policies pursued by Walker and the Republican-controlled legislature, rallied to Kloppenburg’s side. Walker allies feared the potential defeat of Prosser , who called himself  “a common sense complement to both the new [Walker] administration and Legislature.”
While there are just a few hundred votes  separating the two candidates, guaranteeing a recount, last-minute spending by right-wing organizations helped salvage Prosser’s flagging campaign.
According to the Brennan Center for Justice of New York University , which monitors spending in judicial elections, pro-corporate groups have greatly outspent progressive organizations. The Brennan Center found that spending in the race passed the $3.5 million mark , with most of the spending benefiting Prosser.
While the Greater Wisconsin Committee ran ads against Prosser’s reelection, pro-corporate organizations such as the Wisconsin Manufacturers and Commerce (an amalgamate of the Wisconsin State Chamber of Commerce and the Wisconsin Manufacturers Association), the Club for Growth, Citizens for a Strong America, and the Tea Party Express have flooded the state with ads supporting Prosser and berating Kloppenburg.
As of Monday, the four groups which backed Prosser spent a combined $2,177,220, but the Greater Wisconsin Committee spent $1,363,040. The final spending figures have not yet been tallied.
Citizens for a Strong America, a front group  for the Koch Brothers-financed Americans for Prosperity, ran an ad so erroneous that the nonpartisan group PolitiFact gave it a “pants on fire ” rating. Even the far-right Family Research Council added to the smear campaign , attacking Kloppenburg, who worked as assistant attorney general since 1989, as inexperienced in advertisements on thirty-four Wisconsin radio stations.
With a recount pending, Kloppenburg’s come-from-behind campaign shows the ability of progressives in states like Wisconsin to overcome the corporate juggernaut that is able to spend almost limitless amounts of money to support its favored candidates.
