My new imaginary hip white friend

I am not really a supporter of Barack Obama, although I suspect I would vote for him should he become the Democratic candidate, but I have grown tired of him constantly being referred to as the "black" candidate, imaginary or not. He is exactly as white as he is black. Why doesn't anyone ever refer to him as just another white candidate or do Jim Crow rules still apply?

From this point forward Barack Obama is my hip new imaginary white friend and I want no arguements from anyone!
