What qualities do people look for in elected (or unelected) leaders? The question applies to all areas of life, not just politics.
What qualities stimulate people to "follow," or choose, a leader? Among others, physical presence, ability to speak, self-confidence, and reliable decision-making play important parts, but some of it is difficult to express. This post stimulates the discussion: What is the "Presidential Presence"?
One component of it, perhaps not a large one, is a person's aptitude for being a target of positive transferences. That, plus the power, is what transforms an employee of the citizens (ie a politician) into something that seems special, probably too special. After Washington, my favorite President was Coolidge.
When it comes to politics in the modern era, one part of it is simply celebrity. "Charisma." TV, video, and film create celebrity, as in "famous for being famous." What qualities support that? Why does anybody listen to, or pay attention to, celebs?
