Here is the infamous quote:
You start out in 1954 by saying, “Nigger, nigger, nigger.” By 1968 you can’t say “nigger”—that hurts you, backfires. So you say stuff like, uh, forced busing, states’ rights, and all that stuff, and you’re getting so abstract. Now, you’re talking about cutting taxes, and all these things you’re talking about are totally economic things and a byproduct of them is, blacks get hurt worse than whites.… “We want to cut this,” is much more abstract than even the busing thing, uh, and a hell of a lot more abstract than “Nigger, nigger.”
It's not that the words are new. This quote has been around and known since 1981. What's new, thanks to Jimmy Carter IV's work, is that we now have audio to accompany it:
This is an exclusive from The Nation. It is quite something to hear the actual words spoken, as well as hear them in their complete context (which doesn't make them any better). There is complete audio of the interview at the link.
This is the GOP strategy since 1968, and it continues today.
