Black voters broke for Biden — but will that lead to victory?
This might come off as racist, but I'll say it anyway and accept the consequences.
White liberals, for all their talk of inclusion and diversity, are really only concerned with the affairs of other white people and think non-white people are inconsequential. They might not openly support white supremacy, but it is baked into their worldview.
The black vote is extremely important in the Democratic primary, but I don't think a lot of white liberals really believe that. That is why in 2016 they sat around in stunned disbelief when a candidate with no pull with African American voters lost to the most hated politician in history, who had a lot of sway with black voters. What's more, I don't think they understand the sheer economic, educational and ethnic diversity of black Americans. Instead preferring to view all black people as a monolith of uneducated, poor people living in the "hood".
I don't think Bernie Sanders made any real attempts to appeal to the black community in the past four years and now he is paying for it.
