Barack Obama, D-Ill., shows the presidential hopeful, Obama, in 1979 during his high school graduation in Hawaii with his maternal grandparents, Stanley Armour Dunham and his wife Madelyn Payne, both natives of Kansas. Growing up as a young man of mixed race, Obama benefited from the spirit of tolerance that defined Hawaii’s racial climate. His childhood in the country’s idealized melting pot was far from painless, though. (AP Photo/Obama Presidential Campaign/file)
