It is a flowing narrative from the time of slavery to the Civil War and on to the nation's struggle for racial equality. That story includes Martin Luther King's life and death as a martyr. Today the story continues in a nation where one-third of the population is made up of racial minorities. There is also an unprecedented number of immigrants and record levels of prosperity among the black and Hispanic middle-class. Now we have Barack Obama's astonishing political rise, advancing the story to the point where a majority white nation might possibly select him as its first president of color.
