I refer you to the following three Internet articles.

I particularly direct your attention to the portion which reads:

"Mr. Obama is 50% Caucasian, that from his mother. What those who want Mr. Obama to write history by becoming "America's first African-American president" ignore is that his father was ethnically Arabic, with only 1 relative ethnically African Negro - a maternal great-grandparent (Sen. Obama's great-great grandparent, thus the 6.25% ethnic contribution to the senator's ethnic composition.).

That means that 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.

Put another way, his father could honestly claim African-American ethnic classification. He was the last generation able to do so.

Sen. Obama could honestly say, "My father was African-American." Racist presumptions led an Ivy League admissions committee, and lazy "newspapers of record" factcheckers, to presume that if his father is African-American, then Sen. Obama must be African-American also.

But it doesn't work that way. Racist presumptions coupled with sloppy vetting don't turn a lie into the truth.

Sen. Obama is one generation too far removed from the ethnic African Negro input to make the same claim as his father, Harvard's Admission's stamp of approval notwithstanding.

As you can see for yourself, Sen. Obama's African-American ethnic claim, when properly researched and documented, is a lie.

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."
[Emphasis added by me, Curious]

You will also note that the writer of the first and second article go further to assert that research into the ancestors of the candidate’s natural father show that they were slavers, i.e., they captured negroes (see the first article which says that Negroes is a scientific term for that ethnicity) and sold them as slaves to others – about 10.5 million were sold to Caribbean plantations and 500,000 were sold to American plantations before importation of slaves into the U.S. became illegal in 1803.

I am repulsed by slavery, and all of its aspects. I pray that people who enslave other persons get the hottest and most painful part of Hell (Obama’s ancestors included).

Color does not matter to me and does not affect my vote either way. But, Obama is running to be the first black president and that puts it into issue.

When he stops running as a "Black" (which he should) – all of this stuff becomes irrelevant (which it should).

Thank you for your inquiry.
