The deep-pocketed, fiscally conservative advocacy group Club for Growth announced endorsements today of former state Sen. Barry Loudermilk and surgeon Bob Johnson in their U.S. House GOP primary runoffs.

The Club can channel funds to the candidates and spend big on independent advertising. This week it failed to unseat U.S. Rep. Mike Simpson, R-Idaho, despite putting $500,000 behind Simpson's primary challenger.

Loudermilk, of Cassville, faces former U.S. Rep. Bob Barr, of Smyrna, in the 11th District runoff. Johnson, of Savannah, faces state Sen. Buddy Carter, of Pooler, in the First District runoff. Here's the full release from the Club:

"ObamaCare is a disaster, and sending Dr. Bob Johnson to Washington is just the prescription we need," said Chocola. "Dr. Bob Johnson will never stop fighting to repeal ObamaCare, and he'll oppose wasteful earmarks and reckless spending in Washington. Voters in southeast Georgia have a clear choice in Dr. Bob Johnson and the Club's PAC will do everything necessary to elect him to Congress."

The Club still has not weighed in on the Senate race, and it's unclear if the runoff matchup is enough of a contrast for the group. Jack Kingston has an 83 percent lifetime score from the Club -- far from perfect, but well ahead of folks like Simpson and Sen. Thad Cochran, R-Miss., who got the full-court press to oust them.
