First and foremost i do believe that President Barack Obama was born in the United States and he is thus a bonafide US citizen.
By most African customs and traditions on the other hand is is a legitimate Kenyan by the virtue of his father having been a born and raised a citizen of Kenya. In many of our traditions he would not have been so considered if his genetic code had been one, whereby his father was a european american and his mother an african ( kenyan ). So then people, we have a duo consideration of the US president, that he is in fact a US CITIZEN for having been born on american soil thus making him a legitimate US president and by african tradition he is also a Kenyan by virtue of having been fathered by a Kenyan citizen.
