I have now heard the argument from many people that "Ron Paul cannot win." While I disagree, I would also like to direct said people to this article which contains a letter about why a Ron Paul candidacy will help America even if he does not win. Ron Paul opens a dialog which we have not seen in American politics for many, many years. He inspires people who are not interested in politics to join the process. Believe me, I've met them. Many of his supporters are people who have never been involved in politics before. I have met these people in real life, not on the internet. Ron Paul supporters are real people and we want Americans to start discussing the important things about the role of government in our lives, in foreign policy and in a host of other subjects.
Edit: And for those of you who cannot get my local news station, here is the coverage of our rally of which I am a part. The picture of me is not all that clear, but it's in there.
