Americans for Prosperity released a new radio spot last week criticizing former New Hampshire Gov. Jeanne Shaheen for her energy plan, including her opposition to offshore drilling. Shaheen, a Democrat, is currently running for Senate.

Americans for Prosperity is spending $122,000 on the ad, according to a recent Federal Election Commission filing. The group — which has received financial backing from conservative billionaire and former Libertarian vice presidential candidate David Koch — promotes free market policies, lower taxes and limited government spending.
