Emanuel used the term to describe a select group of liberal Democrats which leads me to believe that Sarah needed a quick sound bite prior to her speech at the Tea Party festivities in Nashville (sell those books). Her attempt to equate the word retarded with the N-word is IMO an insult to African Americans. Finally, upon careful consideration of both the target audience and the course of action proposed by that target audience...Emanuel's use of the word was accurate.
