Rick Santorum stirs his ever-growing crowds when he promises to right a country awash in "immoral debt" and to replace an administration he argues has, in his words, "callousness toward life and family and faith."
Of the GOP presidential hopefuls, Santorum is by far the most emphatic about his faith. He draws on his Catholicism and deeply held views on social issues. It serves to solidify his standing among religiously motivated voters - and subtly remind them of lingering reservations of opponent Mitt Romney's spiritual background.
When the GOP field was at its fullest, several candidates were fighting to be the favorite of conservative religious voters. Now, Santorum is moving to consolidate that wing of the party.
