It's possible
that the Obama camp see that Rev. Wright just isn't going to go away during the primaries and they have been given advice from the Dems that are going to make him the nominee to just burn out the issue, oversaturate the media with it til the country gets sick of talking about it so that it truly is behind him for the general. I'm not sure that's a great strategy but any other requires him selling his soul which I really don't want him to do.
