I guess one (perhaps borderline ASB) possibility is that the genre becomes much more dominated by "outlaw country" and its cousins, and artists who attracted political controversy like the Dixie Chicks and Steve Earle are almost par for the course. Though if that happened, then probably a lot of the people who see country as unsophisticated and "red state" would instead like it or at least respect it, so I'm not sure that quite fits the bill of the disco treatment in the sense of almost everybody turning against it.
