It might not be a shock to some, but it turns out there haven't been a lot of nice things said about Wisconsin's gubernatorial race. According to a new study, it's the least positive governor's race in the country.

The Wesleyan Media Project, which tracks and analyzes campaign advertising throughout the country, found that just 3.7 percent of the mid-September ads in Wisconsin's race for governor were positive.

Wisconsin has the fifth highest percentage of negative ads for the same period of time, at 61.5 percent. Maryland topped that list, with a whopping 82.1 percent.

About one-third of Wisconsin's ads — 34.8 percent — were classified as "contrast" ads, mentioning both the favored candidate and his or her opponent.

Ads that only mention the favored candidate are coded as positive and ads that mention only the opponent are filed as negative.
