Perhaps overshadowed in a primary season that has come to be defined by the noise of the tea party movement is the current winning streak of a much older conservative powerhouse: the anti-tax Club for Growth.
A day after GOP House candidates Tim Scott and Jeff Duncan won their respective runoffs in South Carolina, Club for Growth President and former Rep. Chris Chocola (R-Ind.) was crowing about the rise of Generation Club.
Those wins come in the wake of GOP Rep. Tom Graves special election victory in Georgia earlier this month and a pair of Senate primary victories by club-backed candidates.
Even in a cycle when various tea party and right-leaning interest groups are trying to put their marks on the midterm elections, the club continues to earn high praise in the conservative community.
No organization has done more to elect economic conservatives over the past decade than the Club for Growth. Its principled, effective and feared by Democrats and Republicans alike, said Matt Hoskins, spokesman for Sen. Jim DeMints (R-S.C.) Senate Conservatives Fund Political Action Committee.
If there is a criticism in conservative circles, it seems to be that in such a Republican-friendly year the club could be taking a few more risks with where it decides to play.
The clubs next chance to extend its primary winning streak will come in late July in Oklahoma, followed by a pair of primaries in Kansas and another in Tennessee during the first week of August. All those contests are in safely Republican open seats.
In fact, when it comes to House races this cycle, the club is so far only playing in safely Republican open seats.
The real battles between the club and the party establishment have played out in Senate primaries.
It so happens that in this cycle, with the Republicans in the minority and Obama in the White House, the House Republican caucus has been unified and supportive of the clubs positions, said one GOP strategist with ties to the Club for Growth. On the Senate side this cycle, the club has shown itself very willing to buck the party establishment, with its successful effort to unseat Bob Bennett and its willingness to back Marco Rubio and Pat Toomey long before they became the partys standard bearers.
The club also backed Sharron Angle in Nevadas Senate GOP primary when it was clear that the party establishment was behind Sue Lowden in that contest.
The move by the club this cycle to only play in safe, open-seat races in the House as well as indications that the club will play a larger role in general elections this fall than it has in past cycles has been welcomed by those who have criticized the group in the past for being a hindrance to the National Republican Congressional Committees efforts to pick up seats.
The mentality last cycle was every man and woman for themselves, one GOP operative said of the battles between the club and the NRCC. That year, the clubs current or past involvement in House GOP primaries was a major contributing factor in the partys loss of three seats: Idahos 1st district, Michigans 7th district and Marylands 1st district.
Vice President Joe Biden waits to conduct a mock swearing-in ceremony with Sen. Brian Schatz, D-Hawaii, in the Capitol's Old Senate Chamber, December 2, 2014. Schatz was sworn in to serve the remainder of his term since he was appointed to the seat after Sen. Daniel Inouye, D-Hawaii, passed away.
