Short version is this: the head of the Freedom Foundation (an "East Side Group", according to the radio station) wants to change the name of Pecan Valley Drive between Martin Luther King Blvd and Rigsby Ave to Barack Obama Avenue. (It's a pretty long road, and I believe most of it would be unchanged.)
Once you exit I-10, you come to a T-intersection. Hang a left, and you're on MLK; hang a right and you're on Pecan Valley. The freeway exit sign now says "Pecan Valley Dr/M. L. King Dr" The symbolism inherent in this is obvious.
Some folks have suggested any such honor should wait until the President is out of office and no longer a political figure. Otis Thompson, head of the Foundation, says this is nonsense. His desire to rename the street has absolutely zero to do with politics; it's just a way to recognize the nation's first black President.
"I think that now is a good time to do this during the campaign, because it's on the people's minds, the voters minds."
