Innovative products, especially cool and useful ones, have a chance to spread virally. That is what happened to Ron Paul. The success of the product, it's survival and opportunity to transition to the mainstream ultimately hinges on its perceived value -- how compelling is the need to buy. In respect to RP the key is IMO for people to understand how grave our country's situation is right now. The compelling "need to buy" would follow. So a possible approach would be two pronged:
1) Ron Paul needs to communicate better for the general masses. (Not only for people who already understand the economic, political and social background and mechanisms of the issues.)
2) The masses will need to be informed about the realities of today. The MS propaganda will not allow this, but there are alternative sources that at this point not to many people are using. The only, and the best way is marketing by THE WORD OF MOUTH. Talk to you neighbors/friends/colleagues about your concern for your future, your family future. At the end mention that you are looking into Ron Paul as the only candidate "who gets it". But don't push Ron Paul. Your audience needs to go and do their own work. They'll come back to you with questions, or you may check with them in a week: "Did you check Ron Paul out?". Many people will and many will not, Again that goes back to early adopter kind vs. middle of the road kind of minds.
There is no perfect or sure approach here. But not having top notch strategic campaign team that understands modern marketing and issues relating to an innovation adaption is usually detrimental.
