As Jay mentioned, in her interview with Hugh Hewitt, Sarah Palin describes herself as not being a member of any church:

HEWITT: Do you think the mainstream media and the left understands your religious faith, Governor Palin?
PALIN: I think that there’s a lot of mocking of my personal faith, and my personal faith is very, very simple. I don’t belong to any church. I do have a strong belief in God, and I believe that I’m a heck of a lot better off putting my life in God’s hands, and saying hey, you know, guide me. What else do we have but guidance that we would seek from a Creator? That’s about as simple as it gets with my faith, and I think that there is a lot of mocking of that. And you know, so be it, though I do have respect for those who have differing views than I do on faith, on religion. I’m not going to mock them, and I would hope that they would kind of I guess give me the same courtesy through this of not mocking a person’s faith, but maybe perhaps even trying to understand a little bit of it.

At first, it appears striking that such a favorite of religious conservatives doesn’t belong to a church, but I think all those reports about Palin and the Assembly of God did not say definitively that she was actually a member of the church. In a wider sense, not being a formal member of a church is not at all unusual among evangelicals today.

Oh, and by the way — I don’t think Barack Obama is a member of a church now, either, although he used to be.
