The NASCAR auto racing betting season has boiled down to an awfully interesting story line. The betting auto racing points leader so far in the NASCAR competition is Kyle Busch, who is putting together one of the most impressive auto racing betting seasons in memory. But the man just behind him is the ever popular Dale Earnhardt Jr., the man who took Busch’s job at the conclusion of the auto racing betting last year and this battle should set up a very interesting conclusion to the betting auto racing season in NASCAR.
