Democratic contender for governor A.J. Balukoff has outspent incumbent Gov. C.L. "Butch" Otter on television ads, Kimberlee Kruesi of the Associated Press reports.

The nonpartisan Center for Public Integrity released an analysis of political television ads Wednesday that concluded that Balukoff had spend more than $500,000 on some 2,800 statewide television advertisements by Sept. 8. During the same period, Otter spent almost $121,000 on more than 500 political television ads.

The analysis determined that the ads have not attacked the candidates' opponents. The report did not include information about radio, online or direct mail ads, nor did it include information about money spent on local cable channels or production costs, and full political ad spending may be much higher for both candidates. 

According to the report, spending on television ads is sharply higher this campaign season than it was in 2010, when Idaho gubernatorial candidates spent a total of $161,440 for 1,391 ads.
