All politicians are going to mask to some degree in order to present themselves in away they think will get them votes. What's different in Obama's case is that he's wearing a racial mask, this 'bargainer's' mask, and I think very effectively, whereby he gives whites the benefit of the doubt. He's essentially saying, 'I am going to presume you are not racist, if you won't hold my race against me.' So, his mask is a distinctly racial one.
