I’m thinking that I personally have focused too much on race/ideology/age and not enough on region in this primary. Sanders did terribly in the South in 2016. And it seems like he is doing poorly in the South in 2020, based on what we know about Virginia, North Carolina and South Carolina. And part of that story is about race (lots of black voters in these states, and they have backed Clinton/Biden). But the Virginia and North Carolina exit polls tonight suggest he is losing the Southern white vote in those states too.
