This is an extraordinary cultural document. Like Alice Guy's "The Results of Feminism," it's a jokey send-up of a social "absurdity" that was really a historical inevitability. Little Rufus' campaign is a catalog of racist trash - "free pork chops with each vote" and a "dice president", but then all of a sudden Ethel Waters starts singing a cutting and heartfelt ballad about the American dream. It's a shocking moment of raw passion and hope for the future.
