A very funny piece about the faith-based presidency:

His basic point is: the Bible isn't exactly a bastion of democracy. You know, if anything, God is mainly an autocratic figure. You could argue that the New Testament is more about power to the people (though it still does mainly promote blindly following Jesus), but the Old Testament is pretty much, "Do what God says without question."
Bush seems like a kind of Old Testament sorta guy.
