Revolutionaries who come to power by force of arms usually have great crimes in their background. Leaders who survive campaigns by great powers to destroy them do not survive because they observe the niceties of law. Subversives who shape world events by covert action and violence work in shadows and detest the light of day.
Romney is a classic case of re-invention. As governor of Massachusetts, he supported government-sponsored healthcare, was sympathetic to gay rights, and opposed harsh restrictions on abortion. After measuring the difference between the Massachusetts electorate and the national one to which he must now appeal, he has reversed those positions.
