Barack Obama is the new man, of course. His mixed race is a symbol of that....But maybe it's not so simple....I don't know how Barack Obama's parents met. But the Kincaid article referenced above makes a very convincing case that Obama's family, later,(mid 1970s) in Hawaii, had close relations with a known black communist intellectual.
Oh, just go read it. It gets battier and scarier, the deeper into it you read.
