I think that would be some ridiculous number, like 50. Not going to happen.
Yeah, the Club for Growth doesn't have the resources to take down that many incumbent Republicans in primaries - but I'm sure they will try anyway.
And now this will become a war between me and bullmoose, htmldon, etc. 
And that's the problem. I don't want a war with you, I want a majority in Congress. Moderates don't have an organization that attacks conservative GOP incuments to take them down in primaries,so that Dems can win.
