The group, called "Alaska's Energy/America's Values," is airing a trio of radio ads slamming "Malarkey Mark" for his votes with President Obama on his appointees, ObamaCare and the stimulus and promoting Sullivan, a former head of the state's department of natural resources. They ignore Sullivan's two primary opponents completely.

"Today the American Dream is being suffocated, and Sen. Mark Begich is part of the problem. Begich was the deciding vote for ObamaCare. Now he's trying to duck and hide. Alaska and America deserve better," says one of the ads. "Dan Sullivan is a former Alaska attorney general, commissioner of the department of natural resources, and a lieutenant colonel in the Marine reserves. Sullivan tells it like it is."

"It's time to replace Malarkey Mark with U.S. Senator Dan Sullivan," says another.

A group spokesman says the ad buy is a small investment — $12,000 for five days of radio in the state's major media markets — but that it's a precursor to a larger television buy that will come soon.

Sullivan, a former George W. Bush appointee who has deep ties to some Washington power players, jumped into the race late last year after Alaska Lt. Gov. Mead Treadwell (R) failed to catch fire in his fundraising efforts. He, Treadwell and 2010 Senate nominee Joe Miller (R), a Tea Party candidate, are vying for the nomination in the August primary to face Begich, who's top GOP target.
