The McCain campaign has been throwing around so much mud and smears in recent weeks that it’s easy to miss just how ugly and shameful their character assassination of Rashid Khalidi is. This is an entirely respectable, highly respected scholar. To go further into making a case for him would only be to enable and indulge McCain’s sordid appeal to racism. For McCain, personally, to compare Khalidi to a neo-nazi, it’s just an offense McCain should never be forgiven for. It’s right down in the gutter with Joe McCarthy and the worst of the worst. Khalidi is in this new McCain set piece for one reason — as a generic Arab, to spur the idea that Obama is foreign, friendly with terrorists and possibly Muslim.
