Great video. About 2 min. 50 sec. into it, note the older gent with glasses that comes in from the right to say something to the moderator and walks back offstage. That was Herman Cain.
I should’ve watched the whole thing before posting my earlier reply. Herman Cain appears again at 6:46 in the video when the camera pans right of the center group, with 2 or 3 other black conservatives.
