Ebbie, I probably shouldn't interfere in a US debate but God may well be interpreted as including 'Great Spirit, Yahweh and Allah' but that doesnt help followers of non-theist religions such as Buddhism and Taoism or indeed atheists and agnostics.

In England we have the oddly opposite situation where we have a head of state who is head of the established religion - i.e. Church of England - but where the majority of people have no real concept or knowledge of religion and there are no particular sanctions to being a declared atheist. In fact Blair is seen as a little wierd over here because he actually brings his 'religion' into his politics. It's been 'don't ask and we won't lie' for decades in England.
