I think NASCAR is changing.
As more foreign drives come into the series, more rednecks fans leave the sport.
NASCAR has to balance this equation.
Not even close to reality. There are few non US drivers in all three touring series as a whole and in Cup there only a couple of regulars, Montoya and Ambrose and they've been around for a few years. The southern base backlash was when drivers like Gordon and Johnson, non southern urban types started gaining traction. At look at the TV nubmers will indicate that by far NASCAR is much more popular in the south particularly in smaller markets. It's a myth that the southern fan base is leaving in great numbers.
