Nader says "Talks white"?

Ralph Nader stated that Obama "talks white"? ... what is talking white? To me Nader sounds like he thinks white and black people are some how different? Do we not eat the same? walk with 2 feet? talk with a mouth? and learn in the same schools? Definately looking for attention this man Nader and going about it in a obvious way.... I think only a somewhat closet racist or ignorant fool could agree with his words....
