Can either of you provide some info on the Club for Growth? I've only heard the name...
Club for Growth is Steven Moore's organization, primarily funding conservative challengers to incumbent RINOs to remove them or scare them straight. It also funds conservatives against liberals in competitive races only. It is focused on Congress. It is a fiscally conservative shop, and does not make distinctions or judgments on social policy. They have had great success focusing big money on a very few races that can tip the scales.
Steven Moore is a former CATO top guy, so you have the libertarian flavor of fiscal conservatism. Many other straight conservatives are on the board. Located at: www.clubforgrowth.com
I like those guys a lot, and I've contributed in the past. I'm always looking for the most effective vehicle for conservatism that I can fund. I think they are it, unless someone can point me in a better direction.
