Good luck! I hope this answers most of your questions. I’ve been working on Obama’s eligibility for about six months and have come to the conclusion that he is not a natural born citizen otherwise he would have made public his birth certificate and wouldn’t be hiding documents on which his birthplace had to be stated.
This is an excellent and scholarly link/source-material for the question of Obama’s citizenship(s). Thank you.
