Ron Paul should challenge any of the other candidates to a one on one debate on foreign policy. If they all refuse then he should constantly state that they are afraid of such a debate because all they can do is speak in slogans and are afraid to debate him (possibly mention out of ignorance).
If one of the candidates agrees then Ron Paul should come armed with documents, as well as his knowledge. When debating "why are they coming after us,?" for example, Ron Paul can mention the facts (surveys taken, speeches by Muslim leaders given, CIA conclusions, etc) and after making his point turn over the document(s) (or mention that will do so as soon as the debate ends). Also have additional copies for press and others.
If no one else is interested then surely C-Span would agree to air the debate(s) live.
Ron Paul would crush his opponent. He cannot allow the slogans of his competitor's to stand. He needs to challenge them in detail on foreign policy to show voters who remain ignorant, how suicidal it is to continue our status quo policy. This is really the one issue that is holding him back.
I am sending you this from Europe. Please try and get the attention of Ron Paul and his campaign staff to consider this option.
Thanks
