August 21, 2012- (CNN) – The liberal group Patriot Majority launched a cable television ad campaign Tuesday going after the Koch brothers, who are major supporters of conservative and libertarian causes.
Patriot Majority said it was initially spending $500,000 to air the ads, and expects to spend more than a million dollars by the end of 2012.
"Billionaire oil tycoons Charles and David Koch and their special interest friends are $400 million to buy this year's elections and advance their agenda. What's their payback? Politicians who will pass laws that benefit special interests but hurt the middle class," a narrator in the minute-long spot says.
The ad claims the Koch brothers' donations to politicians are prompted by a desire for policies that would help them financially, including lowering tax rates for the wealthy and changing Medicare to allow private insurers to compete with the government-funded health program on an exchange.
The ad says those policies would hurt the middle class while lining wealthy people's pockets.
