This was an interesting little nugget from Reuters.com. The article highlights the importance US politicians place on religion in contrast to their Euro counterparts.
Honestly, I don't want to say one way or another which approach is right - politicians, like marketers, ask only one question: "what do they want me to say?".
But I will say this: when in the history of politics can you point to a beneficial outcome,or even a civil negotiation, for all parties where someone has said "God is on my side"?
