Here's some spot-on advice for Obama:
He brought it up. He can't use his race as a factor and disqualify it simultaneously. Pick a position and stick to it. Obviously, the better position for Obama is transcending race, and obviously, if he thinks he can dip gracefully into the subject whenever it works for him, he's wrong.Also, after initially denying it, Obama had to concede that he did indeed bring up race with his "dollar bill" comment.
Sigh. (I repeat myself.)
