Your right, Ron's out and it doesn't matter much in the current election.
But....the more his name is out there, the more people hear these ideas. Ron Paul is the first to admit, he is not important himself...but the message is. Less government spending, lower taxes, reform domestic programs that don't work, less military intervention abroad, follow the constitution more closely, vote no on a North American union, Strengthen the US dollar, alternative sources of energy so we can avoid being so dependent on the middle east, secure our boarders, support small business, protect personal freedoms, prevent the federal government from controlling more of your life.
His voice is important because of the ideas that protect us. The gov. serves and protects us. We were not founded as a socialist style country for good reason. We must prevent the semi-socialistic trends.
