BARACK OBAMA’S WINNING map asserted the political dominance of a new, dynamic America, as he flipped blue some of the country’s youngest, most diverse, and fastest-growing areas.

Its political behavior seems tied more closely to antebellum industry than to any of the social changes the country has undergone since.
