Also, over at Daily Kos, David Neiwert on the primacy of racism over economic considerations in voter behavior: https://www.dailykos.com/stories/2020/1/25/1913829/-Why-Sanders-insistence-on-seeking-an-economic-solution-to-racism-is-built-on-hollow-mythology
Reiterating my take on Sanders and racism: Sanders does speak of racism, but obliquely, in the context of 1930s Germany, where economics was a factor. The only candidate to have spoken of racism directly was Hillary Clinton, in her "Two Baskets" speech, and she was blasted for it. While racism was preexisting, the massive economic losses of the crash of 2008 were used to help raise the demon, but I do not believe that ameliorating them will lay it. One cannot unsow the wind.
