There IS a difference between the two parties --yes, they both leave a lot to be desired but still the difference is signifant. The problem is that you cannot trust the RNC, NRSC or NRCC  to allocate contributions on the basis of expressed Repub principles. So, along comes the Club for Growth PAC and solves that dilemma for those of us who want to support conservative/libertarian candidates but don't know who to trust. Great service for the future of freedom! - George Blumel, Atlantis, FL
