How much of the messianic, Beatlemania-like response to President Obama do you think is a product of his biracial heritage? I don't mean in the sense that he is, in himself, a powerful symbol of the colour-blindness that has already been achieved in American society. That's a much-discussed, and obvious, component of his appeal. I am thinking more of the possibility that some people regard him as a sort of messenger or sojourner from a post-racial future in which the varieties of humanity have been whipped together in a big sexy blender. It's a common enough opinion* that miscegenation will ultimately rescue us from the problems of race and that homo euro will one day die, deservedly, of an excess of lust. Does Obama possess a soupçon of extra glamour because we sense that he is, in some regard, the Nietzschean Superman? Do we instinctively recognize him as being a pictorial sample of our likely descendants?
*(Unfortunately for the hypothesis, it seems to be a pretty robust rule that among creole/métis castes, and in places like Brazil or India where something like the racial blender actually operates, people are vastly more conscious of invidious distinctions of hue than they are in merely multicultural societies.)
