Even better - why would a person of 50% mixed heritage - say Obama -
choose to identify himself as black as opposed to white?

That's a choice that is generally made for a person of mixed race by
society at large.

Remember the mixed race kids in school? If they had African Amercan
features, fairly dark complexions, etc, they were normally accepted
far more readily by black students than by the whites. Yeah, I'm sure
there were some blacks who took exception to the mixed kids declaring
themselves "black", but it would not amount to the same degree of
rejection likely to be encountered from some white students if the
same mixed kids claimed to be "white".
