just wondering

Okay, one commentator last night said something about Obama being sworn in with his hand on a bible. Why? I mean, what if he weren’t christian? Well, probably he wouldn’t have been elected in the first place since as a whole America is very provincial and insular, and believing in something other than the Big Three is a sign of being Different or Foreign or Other. Look at the brouhaha in NC with Dole and Hagan, Dole losing in a landslide after calling her rival godless and being rebuffed by Hagan's response about her religious faith.  You can be sure that if Hagan had come out and said, No, I'm not christian, I'm Wiccan that she would not have won that election.  But assuming that he jumped that hurdle, what do you get sworn in on if you think the bible is a piece of fiction?
