Do my political research for me

Years ago, probably on rasff, someone mentioned that Pat Buchanan had advised Richard Nixon to go on pursuing policies that would tear the country in two, because the Republicans would end up in control of the bigger half.

Anyone have a specific reference to such a conversation?

ETA:

beamjockey found it in a New Yorker article.

Buchanan gave this to George Packer, who wrote about it in a 2008 New Yorker article. Memo from "Research" to H.R. Haldeman, 5 October 1971, "Dividing the Democrats." In discussing a strategy to alienate conservative Democrats over racial issues, possibly bringing them into the Republican fold, Buchanan writes:

In conclusion, this is a potential throw of the dice that could bring the media on our heads, and cut the Democratic Party and country in half; my view is that we would have far the larger half. But that is not my decision.
