Newt Gingrich has every right to reshape himself as an “outsider” and leader of the American Tea Party movement. A lifetime career in and around history and politics should be viewed every bit as transformable as a career in any other field. As we have seen with Winston Churchill’s famous popularity/unpopularity/ultimate resurgence there can be as many ebbs and flows in a successful political career as there are in careers involving business, science, arts, teaching, etc.
The prevailing attitude that everyone carries the same values, visions, opinions, and convictions from kindergarten to death is absolutely silly. People grow. They react to events occurring around them. The extent to which people assimilate new knowledge and circumstances, and then take wise action, leads to success.
