His book “No Apology: The Case for American Greatness” is a love song to the idea that this country merits “the protection of Providence” and has a singular “calling” to be a beacon for freedom. A major theme for him on the campaign trail is the nation’s divine destiny, a heritage Romney said has made him “stand a little taller, a little straighter” when overseas.
