#4 Longtime NASCAR fans
Another person that is bound to be negatively affected by this deal is longtime NASCAR fans, who have been increasingly passed over in favor of bringing new fans to the sport. Again, the new owner of NASCAR could go in the other direction and restore NASCAR to its former southern roots glory, but that decision would come at the expense of the newly won fans.
With that being said, it makes little sens for the new owner to focus exclusively on the longtime fan base and it is much more likely that they will continue to try to court a new audience. In the end, maybe this wont be the case and a more conservative buyer will come to the table with hopes of restoring NASCAR to its former glory, but its a longshot at best.
