This is the ethnic break down of B. Hussein Obama:
50% White
43% Arab
7% Black
Only one of his great-grandparents was an African.

...The question no one wants to answer - particularly Mr. Obama and his supporters, is, “Why do you think he has an Arabic name? Why does his father have an Arabic name? Why does every ancestor on his father’s side have an Arabic name?”
The answer is obvious: They have Arabic names because his father’s side of the family tree is Arabic.
Need proof? Research the Kenyan records for yourself. You will find that his father was officially classified as “Arab African” by the Kenyan government...
