Sanders' voters kiss Obama's butt and paint Hillary as the devil. Hillary and Obama weren't very different policy wise. Now we've got Trump. The only outsiders who will win in this racist country are the ones on the far-Right. White heartland voters are conservatives. They're paranoid about their position in the racial hierarchy and jealous of Black achievement and especially they are worried about competing with better educated immigrants and racial minorities. The white ideology is degenerate--look at their candidate, a racist and sex abuser and they're mired in mythological pasts that never existed. They're backward looking, old and can't compete.
