Lee Atwater was a political consultant and strategist to the Republican Party who worked for Ronald Reagan. He did an interview in 1981 with a political scientist who was writing a book, then later the audio was released by The Nation magazine.

But check this out this part of the interview, and keep in mind this is 36 years ago, also the bold text is added by me:

Atwater: As to the whole Southern strategy that Harry S. Dent, Sr. and others put together in 1968, opposition to the Voting Rights Act would have been a central part of keeping the South. Now you don't have to do that. All you have to do to keep the South is for Reagan to run in place on the issues he's campaigned on since 1964, and that's fiscal conservatism, balancing the budget, cut taxes, you know, the whole cluster.

Questioner: But the fact is, isn't it, that Reagan does get to the Wallace voter and to the racist side of the Wallace voter by doing away with legal services, by cutting down on food stamps?

Atwater: 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 forced busing, states' rights and all that stuff. You're getting so abstract now [that] you're talking about cutting taxes, and all these things you're talking about are totally economic things and a byproduct of them is [that] blacks get hurt worse than whites. And subconsciously maybe that is part of it. I'm not saying that. But I'm saying that if it is getting that abstract, and that coded, that we are doing away with the racial problem one way or the other. You follow me—because obviously sitting around saying, "We want to cut this," is much more abstract than even the busing thing, and a hell of a lot more abstract than "Nigger, nigger."
