I believe you are correct,
Do you have any proof?
There is no absolute proof of Obama’s Canadian birth. However, a Canadian birth perfectly fits every single known piece of evidence related to Obama’s nativity, and no other location does. When all the evidence points in the same direction, the resulting deduction is entirely warranted.
Incidentally, I have not heard any proponents of either the Kenyan or HI birth scenarios explain Stanley Ann’s sudden, out of the blue appearance in Seattle. Those would be interesting explanations to read.
