There is a straight line from The City on the Hill to America’s Manifest Destiny, from Oliver Cromwell’s Roundheads to Rick Santorum’s Libertarians and from Charles I to his fellow-Cavalier Mitt Romney. It can even be argued that the American civil war was in some ways a replay of the English civil war, with the Cavaliers in the North fighting the Puritans in the South, the home of the Christian Right.
