Club for Growth is certainly a good start, but perhaps they are a little too 'limited' in their function. Perhaps Conservatives need to emulate some of the forms of the radical left wing. Moveon and the various Soros groups (ACT etc) have certainly been very effective in pulling the D's way left. There is no room in the D party for those that don't toe the radical leftist line. I certainly wouldn't mind if there was no room in the R party for those who can't even stand by the Constitution never mind the party.
I completely agree there, 527s and PACs are the way to go. Let's make this a "Not One Damn Dime" election cycle for the RNC.
