Most negative comments concerning this topic are being made by people who are admittedly not race fans and have no idea of the impact placing even a small ad on a car will do.
This goes beyond anything a blimp or other advertising could ever do. When you advertise on a race car you reach, even in the Nationwide series, well over 50,000 people on a race weekend. Race fans take interest in the cars on the track not some blimp flying overhead or signs posted around the track. When you advertise on a car you gain immediate credibility among the fans.
This effort should be looked at in the long term: If we go to a brokered convention Dr. Pauls message will be viewed by alot of people every weekend in cities from Loudon NH to Fontana CA!!
Some TV exposure every weekend sure, but more importantly people that go to the races, even the Sunday races (Sprint Cup) know about the particulars of the cars that run on Sat. (Nationwide). Sponsoring a car gives you the opportunity to hand out information about Dr. Pauls message and I'm telling you from experience race fans will read the information while sitting in the stands before the race. In my opinion they will like the message, as most people do once they are exposed to it.
In the end, if Dr. Paul gets to and wins a brokered convention and runs against Hill or Bama this 300K could make all the difference come November.
