The YG Action Fund, a super PAC affiliated with House Majority Leader Eric Cantor (R-Va.), is on the radio in North Carolina’s 8th district with an ad backing former Hill staffer Richard Hudson.

The spot, backed by a $53,000 buy, is the second independent expenditure the super PAC has made on behalf of Hudson. On April 24, the group spent $22,750 on mailers supporting the candidate, according to Federal Election Commission filings.

“Richard Hudson will cut out-of-control government spending — starting with repealing and replacing Obamacare,” a narrator says in the spot. “Hudson will fight for tax relief for our families and businesses: He’ll protect North Carolina jobs.”

Hudson, the frontrunner, is locked in a competitive race with four other GOP contenders, including dentist Scott Keadle, who is backed by the powerful pro-free-market group the Club for Growth.

The club and its affiliated organizations have spent more than $300,000 on TV ads and direct mail supporting Keadle, according to FEC filings.

Hudson, a former chief of staff to Rep. Mike Conaway (R-Texas), has the backing of the GOP establishment. He caused a bit of stir in recent weeks when he appeared to embrace the “birther” movement, the false notion that the president wasn’t born in the United States.

The YG Action Fund previously spent money on ads supporting Rep. Adam Kinzinger (Ill.) in his winning GOP primary battle against Rep. Don Manzullo.

The North Carolina primary is Tuesday. If no candidate gets more than 40 percent, a runoff election would be held July 17. The GOP nominee will take on deeply vulnerable Rep. Larry Kissell (D) in November. Roll Call rates the race as Likely Republican.

Republicans in the state said Hudson, despite his competition, will get close to avoiding a runoff but probably will end up going head-to-head with another candidate.
