The only real race barriers remaining are in the minds of the black people. A lot of them still seem to think that it's "selling out to the Man" to work a decent job or live in a "white" neighborhood. They want "their own" to stay in "the hood" where "their people is." Their continuing struggles stem completely from a combination of self-destructive pride and institutionalized self-pity. Yeah, Obama's presidency is a victory. It's not a victory over the white man, though. It's a victory over the self-destruction that the black people have spent over a century imposing upon themselves.
Apparently racism is not dead. Odd, none of the people of all stripes I work with feel that way, not black or white, not Hispanic or gay. Some people may well feel that way on an individual level, I doubt it's a society wide deal.
