Is Barack Obama black? If you click on the previous link, the article states that “Barack Jr., with half-European genes, is very probably more similar genetically to Hillary than to his wife Michelle.”
What would the LDS say about Barack’s blackness? Apostle Mark E. Peterson said “…and Cain shall not receive the Priesthood until the time of that redemption. Any man having one drop of the blood of Cain in him cannot receive the Priesthood.” (Race Problems– As They Affect the Church) 
Hyrum L. Andrus taught “Brother Joseph kind of dropped his head and rested it on his hand for a minute, and then said, ‘… for the Spirit of God saith the Negro has no right nor cannot hold the Priesthood.’ … but I have heard him say in public, that no person having the least particle of Negro blood can hold the Priesthood.” Doctrinal Commentary on the Pearl of Great Price, p. 403
Pre-1978 Mormon priesthood calculator: The human body holds 6 quarts of blood, and Barack is half Black, therefore Barack has 3 quarts of Black blood, which is way more than one drop or particle, so by LDS standards, Barack Obama is 3 quarts Black.
(for non-U.S. readers, Barack is 2.83 liters Black)
