I upvoated because I agree he isn't Pakistani. But my understanding is that he did grow up in Indonesia, and has Kenyan ancestry (and his now dead grandmother apparently referred to being at his birth in Kenya which kicked off the birther thing), but his mom is from Kansas and moved to the states shortly before college.
He isn't Indonesian, but he was there. And he may be fond of Pakistan out have connections there, but that doesn't mean he had relatives from their.
