Obama embodies more than he can know. "Change" is his mantra, but the potential for transformation goes far beyond the kinds of policies pursued in Washington. Those policies are rooted in assumptions sunk deep into the national psyche, and into the structure of memory that gives it shape. War is not necessarily redemptive. Africans are not necessarily disadvantaged. African-Americans are not mere victims. Race, for that matter, need not be definitive. An old story is offered a new ending - which is the beginning America has been awaiting. The day has come.
