Care to show me a quote where GWB says "God is on your side"?????
I think, as some others have pointed out, that that is more of Krattenmaker attributing a certain mindset to George Bush that may or may not be founded. I personally don't have such a quote, and Krattenmaker doesn't provide one.
Read the rest of the article, it has much more to say about the misuse of the name of God by Democrats and I thought they were pretty good points.
