Obama is bilingual...he speaks jive when appearing before his peeps. Furthermore, his world-renowned humility would never permit him to release his stellar college transcripts that would unquestionably make Perry shrink in awe.
According to a 1990 interview with Vanity Fair. Obama learned this at Harvard.
... Barack Obama has a game plan: he wants to tackle the quagmire of America’s inner cities. Federal money alone won’t do it, he argues. The deeper problem is that “those communities are unorganized. We need to get more people planning.” For preparation, Harvard Law School is a “perfect place to examine how the power structure works.It gives you a certain language.” When he’s fluent, he’ll be able to translate the language of the streets into the language of the Establishment, and vice versa. The sense of mission derives in part from his experiences in the Third World.
