You obviously know very little about Ronald Reagan. He was very much involved in politics from high school on. President of high school study body, president of college student council, president of the Screen Actors Guild (already mentioned in previous post). His father was the local director of the Works Progress Administration, a federal agency created by Roosevelt to provide work for jobless Americans, so even in family life he was exposed to politics. Try to get your facts straight, eh?
Take a few minutes to read a brief biography of the man.
