IIRC, even in the Goldwater-Humphrey counties with few blacks, it was about the vote being split three ways rather than two ways, and Humphrey still getting a lower % than Johnson.
Again, what were these counties? none come to mind.
There were counties like that in lower South Carolina. Also Chatham County, Georgia. I wouldn’t say they have “few” blacks, they’re white majority with sizable black minorities. In South Carolina especially, the white vote was divided between Nixon and Wallace, enabling black voters to deliver plurality wins for Humphrey in certain counties.
