President Ronald Reagan was fond of borrowing from the words of John Winthrop when referring to America as that “shining city on a hill.” Like Winthrop, Reagan was describing the America that he imagined. An America that was free, was respected around the world, and that bridges, not walls, would create shared prosperity with our neighbors. It was a far cry from today’s political rhetoric that’s not only dividing a country and its neighbors, it’s also dividing a political party.
