Is there a catalog of conservative factions somewhere?

[Poll_Blind]

I noticed, and maybe it was a mistake on my part, but I thought I noticed the concept of "NeoCon" kind of being phased out for "Tea Bagger". But I don't think they're the same thing by a long shot. In the same way that you could probably break down elements of the Left into a number of different subgroups or factions, has anyone taken a serious stab at doing this for the Right?

Or the John Birch Society, for instance. That sort of thing. Is there a list with general ideological breakdown?

Thanks!
