How about this one for a starter? "If so, the question then would be, "did that act confer Indonesian citizenship?" If so, where are the documents that "restored" his U.S. citizenship, if indeed he was natural born? "
The answer to the first part is easy; under Indonesian law even if Soetoro did adopt him then that would not make Obama an Indonesian citizen. As for the second part, even if he had been adopted by Soetoro and even if that adoption conferred Indonesian citizenship on Obama, that still wouldn't impact his U.S. citizenship status at all.
It is the same old stuff in a different wrapper.
