The NCAA men's basketball Final Four takes Saturday in Arizona. There will be a Carolina feel in the desert air, as both North and South Carolina will be playing. It's the first time the Gamecocks have made the Final Four, while for the Tar Heels it's their 20th, the most of any school in the nation. Basketball isn't the only thing making national headlines from the Carolinas. Politics and personalities from both states are too. Western Carolina University political science professor Chris Cooper co-authored the book “The Resilience of Southern Identity”. He spoke with BPR's Matt Bush about the state's identities, histories, what makes them different, and how recent events are changing both state's national perceptions.
