Just wondering: Is Obama a "typical" half-white, half-black person?

Obama likes to call his white grandmother a "typical white person."

So I started wondering if Obama himself is a "typical" half-white, half-black person.

Myself, I don't know what a "typical" half-black, half-white person is all about.

Maybe someone here can tell us what a "typical" half-white, half-black person is all about. mirse
