Under "Articles" on this website is a fairly comprehensive background on BO and extended family. It compares BO's "official or public version" of himself with documented facts, that bear almost no resemblance to his public persona. It's quite lengthy, but well worth the read. The article includes backgrounds/genealogical histories on his family members as well.
Of note, there is also a similar research article on McCain.
IMHO, BO was chosen by TPTB long ago. He is NOT who he has been presented to be. Neither is McCain, but he's not the subject of the OP.
As an aside, those of you in the US, if you haven't listened to Michael Badnarik's Constitution Class, I highly recommend it. Sounds boring I know, but truly it's not. It's available on google videos in 7 one-hour parts. I have found that recommending this series of videos to people who need to wake up and learn the truth for themselves has had the best response from friends and family. Awakening is a difficult and often lengthy process for most. It simply cannot be accomplished in a single video or concept. People need something that opens their eyes immediately, makes them say WTF, and gets them interested enough to seek further truth on their own.
You don't get labeled a conspiracy nutso near as often either.
