I don't see this, or any other controversy relating to BHO, as an "attack". These are relevent issues of his own doing. He's chosen to associate with people like Wright, Ayers and now El-Hady. I think it's very important for the country to see just who this guy hangs around with. These are not attacks, they're facts. Real scary ones too. To me, anyway.
Think about this; what if it became known that McCain associated himself with David Duke and Eric Rudolf or he received funding and support from the Church of Jesus Christ-Christian? (Google 'em.) How would most Americans react to these revelations? There is NO WAY McCain would be as close to the presidency as Obama is right now. No way.
