The Club for Growth PAC endorsed three incumbents on Thursday, two of whom face competitive general elections.   

“The Club’s PAC is always looking to add new economic conservatives to Congress, but there are times when it’s crucial that we defend the ones who are already there,” Club for Growth President David McIntosh said in a statement.  

The club backed Iowa 1st District Rep. Rod Blum, one of Republicans’ most vulnerable incumbents. He’s facing Democrat Monica Vernon in a district that President Barack Obama twice carried by double digits.   

Blum has had a tenuous relationship with the National Republican Congressional Committee over his past vote against John A. Boehner for speaker, but he thinks he’ll have the committee’s support this cycle.   

Blum has an 89 percent lifetime score from the club.   

The club also backed New Jersey Rep. Scott Garrett, who has a 95 percent lifetime score.  

The 5th District Republican has also had a difficult relationship with the NRCC. He’s refused to pay dues because of the committee’s support for gay candidates.  

Garrett serves on the Financial Services Committee, but much of his fundraising from the financial sector has dried up.  

Democrats are making Garrett a top target . He’s facing former Clinton speechwriter Josh Gottheimer in November.   

Kansas Rep. Tim Huelskamp does not face a competitive general election, but he still has to get through an August primary in his Safe Republican district. He has a 100 percent lifetime rating from the club.
