Don Quixote’s Thought for the Day: “Retarded”

I don’t have a lot to say about the “retarded” comment by Rahm Emanuel or Sarah Palin’s response, although she certainly has every right to be especially offended.  My question is, if a Republican made the comment, would he keep his job, and if a Republican made the comment would Palin and other Republicans be calling for his head.  I have no real feel for this, but I’d be interested in the comments of those who do.
