Not obvious at all, Jake. Not obvious at all.
Regardless of where Obama was born, he was born to a Kenyan foreign national. Obama IS by that birthright a Kenyan. Unlike it was suggested earlier, we're not talking about ancestry (that would be through grandparents or farther down the family line, not parents). That Obama might be half American doesn't mean that he's NOT Kenyan. In a strict sense, he is Kenyan American (which is much more accurate than calling him African American) and not just American.
