Why is Obama Black?

The definition of "black" came from America's historical classifications, some of which can be read about here:

It is also known as the "one black ancestor rule," some courts have called it the "traceable amount rule," and anthropologists call it the "hypo-descent rule," meaning that racially mixed persons are assigned the status of the subordinate group. This definition emerged from the American South to become the nation's definition, generally accepted by whites and blacks. Blacks had no other choice. As we shall see, this American cultural definition of blacks is taken for granted as readily by judges, affirmative action officers, and black protesters as it is by Ku Klux Klansmen.
