Every time you turn around, a presidential candidate whips out his Bible—or a position paper—to let us know how faithful he or she is. Senator John Edwards (D-N.C.) says God "would be happy with the fact that" he's focused on people without health care. Senator Barack Obama (D-Ill.) says we should "discuss religion . . . in the positive sense of what it tells us about our obligations towards one another." Republicans, also, are quick to point out how faith informs their policies.
