Barack Obama spoke at length yesterday on the issue of race in general and his former pastor in particular. If you haven’t already seen and heard the speech, or read the transcript, I encourage you to do so. There is no soundbite that can do justice to the importance and brilliance of his message. If there was ever a politician who could legitimately argue that he’s a uniter and not a divider, it is Barack Obama. I only hope it helps him win in Pennsylvania.
