Is the "Kanye West will definitely siphon off lots of black votes" talking point racist?

I mean, it's more extremely bad and lazy analysis than it is racist. Although there are iterations of it which are pretty racist.

Of course it's also true that:
1. if Kanye West actually managed to get on ballot, he would receive at least some votes from every race and ethnicity
2. very likely the vast majority of his votes would be from non-Hispanic Whites.
