Or British...regardless of the real facts. The legal facts enforce currently support that he was born to British father. And thus aquired British Citizenship at birth as well.
So like Cruz he would have legally been a Brit.
In 1971 he likely did aquire Kenyan citizenship when his legal, namesake father (regardless of the actual fact that are not known) took temporary custody of him.
So Obama is real mutt when it comes to citizenships.
British
US
Indonesian
Kenyan
Remember Birth Certificates are not the highest regarded form of citizenship identification. Passports are. Show the passports - all the way back to the early 1960s....
Lets see that happen...
What other ways are there to prove citizenship to get a passport, other than a birth cert?
Affidavits from parents?
Census records?
