So what.
If you ask most black people in Compton, 5th Ward Houston, Detroit, Miami, North Carolina, or wherever you have a concentration of African-Americans who could care less about politics, who did they vote for, they will say Obama. He got like 90+% of the total African-American vote. A "black president" was always a dream/fantasy for the African-American community.
So what if people don't know anything about politics, people like to see dreams become reality, Obama made that dream a reality.
