What's wrong with Barack Obama's campaign

Though Barack Obama's campaign is going relatively well I still believe that he's approaching some of it the wrong way. What I am primarily talking about is the nature of the commercials Barack's team has been releasing. I was hoping that Barack would be able to step away from the mudslinging and take it in a more positive direction, but it seems that Barack is swinging back with the best of them. Though, yes you do need to respond to some of the insults put in with commercials, you don't need to take it to the next step and throw it right back in your opponent's face. In fact, I was hoping that perhaps Barack and his team would rise above all the mudslinging, but that is obviously not the case.
