Who was the last Republican to win the black vote?

[Karpatsky]

I couldn't find any earlier, but this Gallup info says Stevenson won the 'nonwhite' vote by a significant margin both in 52 and 56. I don't know what the demographics were like in 1952 but I think that means it's probable he won the black vote, but 56 might have been closeish.

I don't have enough posts to add links, search for this:
