To be a Moslem you profess at any age your belief before Muslims & leaving's illegal. So is Sen Obama one?

This does mean that Sen. Obama necessarily knows he is one. It is that he went to school in Indonesia, he may have professed that belief. There are no definitive records kept of who is a Muslim. Although in Malaysia, the religion is recorded on the identity card and it affects burial and there are often disputes as to what religion a rich or talented Chinese is.
