Did he also happen to state whether or not he was a Kenyan?;)
Actually, he did that back in 2006. Though not admitting he was a Kenyan, he did imply he lived there as a child:
From an interview in the Chicago Sun Times back in 2006 he made while returning from his trip to Africa:
He reflected on his trip at the back of a plane on Saturday, talking above the roar of the engines to the three print reporters who have been covering his trip.
Obama's next big international journey will be in 2007--he's looking at China, India and Indonesia, ``where ironically I actually have more of a childhood than I do in Kenya.''
... More of a childhood ? That implies he had some form of a childhood in Kenya. To have a childhood there, he had to have lived there.
