To begin with, there is more than ample proof that this "BC" is a fake. If you're creating a fake BC to cover a fake narrative, why not make things nice and acceptable to polite society, while minimizing questions and inquiries, by just listing the mother's married name.
This may sound far fetched, but given that every time there are serious questions, 0bama trots out an "new" fake BC, is there any real proof that Stanley Ann Dunham was actually his mother? With no BC, 0bama could be just some black baby Stanley picked up in kenya.

Mike Zullo has said in interviews that there is no definitive proof Stanley Ann Dunham was his real birth mother.
Wasn’t 1963 the year that Obama Sr. was about to get kicked out of the country while at Harvard? Could he have contacted StanAnn and pleaded with her to say they were married so he could stay in the country?
