you'll hear of someone running unopposed, especially in smaller jurisdictions. But when it comes to the challenge of great leadership, there are always those who believe they've got what we need.
What is interesting about the United States as a country is that, literally, anybody can run for President. Hollywood actor? Peanut farmer? Soldier? Preacher? Sure! Throw that hat right on into the ring! (Now that doesn't mean just anybody can get elected. But everyone is certainly welcome to try.)
