I don't think I can create a suitable ASCII diagram for you, but there's plenty of overlap -- for now. Tea partiers are first and foremost economic conservatives. The religious right is first and foremost concerned with social issues. But right now they're working arm in arm, with social conservatives (Ralph Reed, Tony Perkins) trying to claim some of the energy of the movement, and tea partiers happily to work with these activists who, by and large, share their beliefs.
"By and large" leaves a lot of room for disagreement, though. If Republicans control every branch of government in 2013, I'd expect many tea partiers to blanch at -- and possibly protest against -- some of the priorities of, say, the Family Research Council. I meet plenty of gay, anarchist, libertarian, and just generally "leave us alone" tea partiers who absolutely despise the Ralph Reeds of the world. It's just that they have a common enemy now and they'll look past it. But the majority of tea partiers are social conservatives, even if it's not what got them into the streets, and they will have no problems working with the religious right.
That's it for me, but I had a great time. My apologies if I didn't answer your question -- come back next time or come right over to the blog and ask it!
