Whatever the final historical judgment of Obama's presidency, the very fact of it resonates globally as it signals that the United States is more in sync with the rest of the world than its power-wielding implies and is ready for the multicultural changes of the 21st century, says cultural anthropologist Sharma. He draws on his insider-outsider perspective as an immigrant, written materials by and about Obama, and interviews with family, friends, neighbors, and teachers in Hawaii and Indonesia to offer the first cultural biography of Barack Obama. . . . Sharma offers intriguing glimpses of Obama's life and a compelling argument that Obama's singular background and his election as U.S. president despite distrust of his "otherness" make him a transformative figure as the United States grapples with emerging nations and its own decline as the world's only superpower.
