I have said many times that he led everyone to believe he was from Kenya until people started talking to him about running for President, during which time he stopped making such claims and started saying he was from Hawaii.
I think he claimed to be from Kenya because he saw it as benefiting his career. He is a habitual liar.
Now we need to find those Obots that we have argued with in the past and shove this new piece of information down their throats!
It also permitted him the opportunity to talk smack against the United States among his peers with the "eyes of an outside observer" (some who knew him then said as much recently).
