Nascar has been the #1 racing series in the U.S. for several years and is now #2 behind the NFL in overall popularity. Fox and NBC pay millions to broadcast the races. ESPN is going to pay millions beginning in 2007. But, why is Nascar so popular? It certainly isn't because the racing is so good, because it hasn't been consistently good for several years. Races frequently become parades and side-by-side racing is the exception rather than the norm. "Aero push" is a worse term than "points racing" and has almost single-handedly ruined Nascar. I submit that if the split hadn't occurred in the open-wheel world, Nascar would continue to be the #2 racing series in the U.S. I wonder what will happen to Nascar if IRL and Champ Car see the error of their ways and get back to one open-wheel racing series. What do you think?
