I think Paul needs to be more restrained in his speaking. I can appreciate his honesty, but it's more important that he become President than be completely outspoken right now.
His honesty can be turned around by the media, which unfortunately - like it or not - has a tremendous impact on who becomes president.
He needs to be more neutral or "political" in some of his responses right now. His positive messages are out there, don't give the media anything to lambaste him on.
Also, I don't agree with his comment on slavery and the Civil War - anyone who has studied the Civil War in detail knows that slavery was only a small part of the equation. That, and slavery drove their economy - a one-time purchase of the slaves would not have worked. I love Dr. Paul, but he came off as being ignorant on the Civil War.
