A lot of people, possibly even the majority, don’t want their worldviews challenged. They want endless goodies. They want checks with their names on them. They want to be flattered. They want: “You are the awesomest of the awesome, and that’s why your government is hated around the world. Because of your awesomeness.”
Someone at this level of moral and intellectual development is not going to understand Ron Paul, much less support him.
