Obama was born into a country where laws barring his very conception—let alone his ascendancy to the presidency—had long stood in force. A black president would always be a contradiction for a government that, throughout most of its history, had oppressed black people. The attempt to resolve this contradiction through Obama—a black man with deep roots in the white world—was remarkable. The price it exacted, incredible. The world it gave way to, unthinkable.
