Tim Noah translates politician body language:
"Something to remember about touching is it's a hierarchical gesture," [Elizabeth] Kuhnke advises. "The person who initiates the touch holds the authority. The doctor touches the patient, the teacher touches the student, and the priest," well, never mind what the priest does. The point is that when Romney put his hand on Perry's arm it was not merely to say, "I would like you to stop talking now." It was to say, "I am superior to you and I would like you to stop talking now."
