Lot's of them. They don't poll well, though.
Obama is looking for a liberal church, but not too obnoxiously liberal. He wants one is relatively bland, where videos of the sermon won't scare anyone. With the recent bowing fiasco, he doesn't want a church with a foreign heiarchy which might bring up questions of his national loyalty (there goes Catholic). No strong opinions on other religions are allowed, so many Baptist churches are out. Are there any really dull Episopal churches near the White House?
Scientology?
