As a non-believer, I appreciated Obama saying that after recently learning about a 1987 interview with George H W Bush:

Sherman: What will you do to win the votes of the Americans who are atheists?
Bush: I guess I’m pretty weak in the atheist community. Faith in God is important to me.
Sherman: Surely you recognize the equal citizenship and patriotism of Americans who are atheists?
Bush: No, I don’t know that atheists should be considered as citizens, nor should they be considered patriots. This is one nation under God.
Sherman: Do you support as a sound constitutional principle the separation of state and church?
Bush: Yes, I support the separation of church and state. I’m just not very high on atheists.

That having been said, rephrasing the third clause to “Buddhists and non-believers” would have sounded just as ‘epic’, and I’m kinda wondering why The One didn’t include the other major religion? Seemed like a huge oversight.
