Majority PAC 2012, Patriot Majority USA Buy $1.6 Million In Ads

Majority PAC 2012 and Patriot Majority USA launched $1.6 million worth of ads Tuesday in four states -- Indiana, Ohio, Montana and North Dakota -- targeting Republican senatorial candidates as corrupt and dangerous for Medicare and Social Security.

The PACs' goal is to keep the Senate in the hands of Democrats, and the four races are considered vital to that effort. Two of the Republicans, Rep. Denny Rehberg (R-Mont.) and Ohio Treasurer Josh Mandel, are running against current Democratic senators. The others, North Dakota Rep. Rick Berg and Indiana Treasurer Richard Mourdock, are running against non-incumbents.

Mandel, who is challenging Sen. Sherrod Brown (D-Ohio), is criticized in an ad for giving jobs to "college buddies and political cronies" rather than focusing on the state. "Josh Mandel: Protecting friends' jobs but not Ohio jobs," a voiceover says.

The North Dakota ad points to Berg's Medicare record and says he wants to privatize Social Security. "Rick Berg is a risk to your retirement," a voice says in the ad. "He's changed. He's gone Washington." The ads against Rehberg and Mourdock are along a similar vein, focusing on their views on entitlements.

Majority PAC 2012 and Patriot Majority USA now have ads running in six states, including Nevada and Virginia.
