Kokesh is an inspiring, passionate speaker, sure. But compare his demeanor to Ron Paul's. They are completely different. Kokesh's intensity frightens many people away.
Ron Paul's calm, good-natured presentation style :o and willingness to listen to any inane question he's asked and really try to respond is what makes him attractive to such a wide spectrum of people.
They are not really comparable in any sense, and I wouldn't support an organization headed by a more militant leader, unless of course that became necessary for survival, in which case I'd be seeking out Kokesh wherever he might be to join up with him. But that's not where we are at right now.
