Which begs the question, if SAD did provide a BC to prove his ID when she was ultimately given custody March 20, 1964, why the need to forge a BC NOW?
The scenario that's emerging for me is this:
BO is born in Kenya.
Underage, unwed mom Stanley provides him with statutory U.S. citizenship and this enables him to get a Hawaiian BC (under "secondary proof of U.S. citizenship" as described at travel.state.gov).
So therefore BO is a "citizen at birth" but only by statute.
Stanley marries Lolo Soetoro, goes to Indonesia, BO is sent back to Hawai'i in 1970.
For some reason there is a custody or citizenship issue and BO Sr. is escorted into and out of the picture to assist in this matter (1971).
BO effectively renounces U.S. citizenship by traveling under a foreign passport or applying for school aid as a foreigner.
BO waves his (statutory) U.S. citizenship papers to show eligibility for his Illinois Senate (earlier I'd said House, my error) and U.S. Senate bids. But, these documents are no longer legally valid because of things that have taken place since his birth.
BO campaigns for President, and now under scrutiny, needs to come up with a version or two of a birth certificate showing he was born on U.S. soil. He totally disregards the fact that his foreign national father renders him ineligible for the office.
It's a mess.
