South Carolina's Indian-American governor Nikki Haley recently dismissed one of her principal advisors when his membership to the ultra-conservative Council of Conservative Citizens (CCC) came to light. Among the CCC's many concerns is intermarriage and race mixing. According to the Southern Poverty Law Center, in 2001 the CCC website included a message that read "God is the one who divided mankind into different races.... Mixing the races is rebelliousness against God. " Beyond the irony of a CCC member working for an Indian-American, the episode reveals America's continuing struggle with race, racial integration, and race mixing.The Color Factor shows that the emergent twenty-first-century recognition of race mixing and the relative advantages of light-skinned, mixed-race people represents a "back to the future " moment---a re-emergence of one salient feature of race in America that dates to its founding. Each chapter addresses from a historical perspective a topic in the current literature on mixed-race and color. The approach is economic and empirical, but the text is accessible to social scientists more generally. The historical evidence concludes that we will not really understand race until we understand how American attitudes toward race were shaped by race mixing.
