from Answers.com among other sources:
Mr. Obama is 50% Caucasian from his mother’s side. He is 43.75% Arabic, and 6.25% African Negro from his father’s side, a great-great grandparent. His ancestors on his father’s side were Arab slave traders. They operated under an extended grant from Queen Victoria, who gave them the right to continue the slave trade in exchange for helping the British defeat the Madhi Army in southern Sudan and the Upper Nile region.
So what percentage of African Negro makes someone black? For that matter, what percentage of Caucasian makes someone white?
Documentation please, on Obama’s % and on the Queen Victoria grant.
Yes, that would hold true if he is actually the offspring of the Kenyan.
However, if (as postulated by some) that his bio-father was actually Frank Marshall Davis or (perhaps even) Malcolm X, then perhaps he has no Arab blood. Perhaps we shall find out the truth some day.
The "answers" on answers.com come from users. You can't possibly take that seriously. Obama Sr was not 90.7% Arab and 9.3% African. A 5 second glance at any photograph of Obama Sr. will confirm this. Not only is his skin tone several shades too dark to be Arab, his facial features and bone structure are clearly African. Even mathematically, those numbers are pure bunk. 90.7%=907/1000 .. 907 is prime. 9.3% = 31/333. How do you suppose Obama Sr. is 31/333rds African? Some moron made that crap up, posted it on the internet, and then people keep repeating it until you have a whole chain of "research". It's bunk.
Just because Obama is the worst president in our lifetimes does not mean he is an Arab. This kind of fringe thinking really doesn't help our cause and I am pretty sure it didn't do much to convince your children of their misguided support of a failed socialist.
