The furor started on Thursday when Rick Davis, Mr. McCain’s campaign manager, said, “Barack Obama has played the race card, and he played it from the bottom of the deck.” Mr. Davis was alluding to Mr. Obama’s remarks on Wednesday that Republicans would try to scare voters by pointing out that he “doesn’t look like all those other presidents on the dollar bills.”...Fighting back? 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.
For Mr. Obama, the risks of fighting back are that anything that calls attention to the racial dynamics of the contest would potentially polarize voters and stir unease about his candidacy, particularly among white voters in swing states. He is, after all, a candidate who has sought to transcend his own racial heritage in appealing to the broad electorate.
[A]t one of his rallies on Friday, where seven self-styled African revolutionaries began shouting and pointing at him, accusing him of undermining revolutionary struggle.Some people will try to lure him into talking much more about race. Friday's hecklers were easy to resist, but the same demand will be made in other, more subtle forms. He needs to stay race-transcendent. Lefties tend to revile race transcendence — to regard it as a kind of racism. I've heard that point of view many times, from very intelligent individuals who express themselves quite rationally and persuasively. They don't shout and point and interrupt. Obama has to resist them too.
