Dick, in this particular case, I don't think it's so much that folks are really interested in seeing Regional results in SportsCar, I believe it's more the inferred attitude of the editor's comment. The implication is that regional races (e.g., Improved Touring) are of little interest to "the most people, over the widest area" (at least that's the way I read it...)

Regardless of if this was intended or not, it's just another blow for the perception that IT is the red-headed stepchild of the club...
