I am not knowledgeable enough about Jesse Benton to have much of an opinion.
Yet, I recall Larry Leopard discussing (in the documentary) a phone conversation regarding a solicitation for donations in 2007, and they admitted that it was unlikely that Ron Paul would win. Yet, he said words to the effect of "If he can get into the debates make a clear case for his positions, then it's a story that deserves to be told." So while, I agree we should try to win, there are potentially great benefits from running and not winning (I had believed in both 2008 and 2012 that there were small but plausible scenarios were Ron could win ). For example, in 2008 when Ron Paul came to the assessment that winning the nomination was not possible, I believe (correct me here I may be wrong on this) he sank a bunch of the remaining campaign donations into Campaign For Liberty. Yet, if Ron Paul had decided to fight his fiercest battle in the primary, wouldn't he have spent every last dime in an effort to garner votes?
