CHARLOTTE -- If President Obama's personal and heartfelt speech on race reached only the ears of Sybrina Fulton and Tracy Martin, it would have been enough. "Trayvon Martin could have been me 35 years ago," the president said, leaving unsaid a parent's dream for a child, the unspoken other side of the equation, that Trayvon Martin could have become him in 35 years an educated man, a husband and father and, perhaps, president of the United States.
