That recalls the notorious Dred Scott case in which the U.S. Supreme Court ruled that Scott had no rights because he was, after all, a slave. The issue turned on whether having resided with his master for a while in slavery-free Wisconsin he could demand his freedom once he was taken to Missouri, a slave state. The notorious Chief Justice Roger Taney ruled against Scott's freedom, thus drawing the cheers of the South. Not only that, he extended the court's decision to all slaveholders who moved their "property" anywhere in America.
Check these words from a chapter titled "The White Party" in Buchanan's book , included in a list of excerpts provided by Talking Points Memo:
'"And although Howard Dean disparages the Republicans as the 'white party,' why should Republicans be ashamed to represent the progeny of the men who founded, built and defended America since her birth as a nation?"
Do you think it was a mere oversight that Buchanan overlooked all of the African-Americans and Hispanic-Amercans who died in American uniforms in the Iraq and Afghanistan wars? Hardly. It's not a neat fit in his rants against too much color.
