The Club for Growth, a leading D.C.-based group of economic conservatives, is blasting former Arkansas Gov. Mike Huckabee (R) for endorsing controversial earmarker Rep.

"Over the past year, the Club for Growth has been criticized by Huckabee and some conservatives for painting the Arkansas Governor as a fiscal liberal," Club for Growth Communications Director Nachama Soloveichik wrote today on the group's website. "If ever there was proof that that the Club was right from the start, it is this outrageous endorsement of Rep. Young who embodies the worst of the Republican Party's wasteful habits."

Huckabee's political action committee, Huck PAC, issued the endorsement last Tuesday. Huckabee praised Young for his attention to U.S. infrastructure.

"When I was a Governor and Chairman of the National Governors Association, he was one of the few members of Congress who fully recognized the direct link between infrastructure and job creation and economic development," Huckabee stated. Young formerly chaired the House Committee on Transportation.

The Club for Growth has endorsed Young's 2006 GOP primary opponent, Alaska Lt. Gov. Sean Parnell, calling Young one of the "most audacious porkers" in Congress, and Young's infrastructure earmarking has landed him in trouble this year: in April, the Senate asked the Department of Justice to investigate Young for his involvement in the $10 million earmark for Coconut Road highway interchange in Florida.

The Club makes a point to oppose incumbent GOP lawmakers whose tax and spending-related votes are too liberal for its liking. It aired television ads that helped defeat GOP incumbent Rep. Wayne Gilchrest (Md.) this cycle and Rep. Joe Schwarz (R-Mich.) last cycle in their primary reelection bids.

During this year's Republican presidential primary, the group accused Huckabee of economic populism akin to that of former North Carolina Sen. John Edwards (D). The group aired ads against Huckabee, who responded to the Club's public attacks by calling it the "Club for Greed" in a television interview.

Today, the group used the endorsement as an opportunity to again level accusations against the former governor based on his record. Soloveichik's online posting refers to Huckabee as a "huge tax hiker," a minimum wage increaser, and a supporter of the Farm Bill (which the Club for Growth vehemently opposes).
