I don’t think McCain was that destructive in that comment. He had already prefaced the evening by saying something to the effect that this wasn’t the day to show conflicts with Obama. He did defend Palin as mayor and that forced Obama to also defend mayors. McCain would have looked petty and mean and that won’t keep those independents coming his way. Since community organizer has gotten so much press as code for black, he would also have appeared racist! And as was already said he didn’t say exceptional service as a community organizer was executive experience.
Not all community organizers are Black. Marxist Hispanic community organizers are following the same militant model of agitation.
