This quote appears on page 155 of Goodwin’s LBJ biography. The utterance was made to Richard Russell, a fellow Democratic Senator from Georgia.

The source of the “200 years” quote is Ronald Kessler’s 1995 book Inside the White House. Kessler got the quote from Robert MacMillan, an Air Force One steward who said LBJ uttered this comment to two governors during a conversation on the Civil Rights Act of 1964.


And as was crystal clear but you still dodged, LBJ's above quote is basically a paraphrase of the "I'll have niggers voting Democrat for 200 years" quote. The same ideas, just without the N-word that he routinely used.
No one disputes that LBJ used the n-word prolifically, and routinely made remarks of his condescending contempt for blacks, and needing to fool them with some illusion of rising status to keep them in their place.

Miltimore in the article thoroughly eviscerates the Politifact attempt to debunk it.
