The Club for Growth hits beleaguered Rep. Don Young (R-AK) with this ad accusing him of pushing for an earmark that would benefit an out-of-state campaign contributor. Young is currently under federal investigation for corruption, including scrutiny of the Florida earmark cited by the ad. Club for Growth has endorsed Lt. Gov. Sean Parnell, who is challenging Young in the Republican primary. The ad buy, which starts today, will cost $350,000, according to the group.
