I don't think Obama can go after McCain too aggressively.
McCain's issues as an angry old man are one thing, but it'd be the end of the election if Obama is ever seen to have an angry black man moment.
IMHO.
Actually, McCain's whole posturing towards Obama might be in an attempt to produce just such a moment. Disrespect (no eye contact, derisory 3rd person), Distortions and Downright lies... hoping to push Obama's temper and switch all those "middle-ground", "I'm not racist, but" types into solid McCain or not-voting types. Oh, and give the noise machine something to repeat ad nauseum for a month.
Conspiracy!
