The conservative Americans for Job Security has launched a media campaign against Wyoming Republican Sen. Mike Enzi charging that in 2010 he had "praised" the state's healthcare exchange, according to Politico.
Enzi is under fire by the group because it says he supports liberal big government and Obamacare.
The 30-second spot has a female narrator saying: "The Obamacare exchange was launched in Wyoming. At a White House conference with Barack Obama, Mike Enzi praised them."
A clip of Enzi can be seen in the ad, where he says, "I like the exchanges. These exchanges can be good."
The narrator says, "Good? Wyoming's Obamacare exchange has the most expensive premiums in the country, and it's marred by glitches."
Kristin Walker, an Enzi spokeswoman, told Politico the senator consistently "advocated for free enterprise solutions that will bring down prices which could have included exchanges. However, the exchange implemented under Obamacare is a system Mike Enzi has always opposed and continues to fight against."
Walker told Politico the ad was silly because no one opposed Obamacare more strenuously than Enzi.
"He worked vigorously during negotiations to stop the worst parts of the law," she wrote Politico in an email. "It is because of Mike Enzi and his Republican colleagues in the so-called 'Gang of Six' that we don't have a universal, single payer system today.
"Mike has been supportive of a market-based solution that allows consumer choice across state lines – with no government mandates whatsoever," she concluded.
Americans for Job Security, which was founded some 16 years ago, has spent millions of dollars on political advocacy and is run by a group of young political activists, according to The New York Times.
As a non-profit it does not have to report the identities of its donors to the Federal Election Commission.
Enzi is facing a Republican primary challenge from Liz Cheney, the daughter of former Vice President Dick Cheney.
