Spot on from law/sociology/political science professor Michael Yarbrough:
I get the feeling that most people see that man's recent tweets as just a spontaneous expression of his racist id. That's not at all what they are. Read them again. They were written, probably for him by a staffer (probably Stephen Miller). Watch how the back and forth has played out since then. See how elected Republicans are responding. Connect it to the way they're handling the concentration camps. What we're seeing is the deliberate roll-out of his 2020 message. He's campaigning on open white supremacy.
This is important because when white supremacy is one side's platform, there's no such thing as a middle ground. You either stand resolutely with multiracial democracy, or you support white supremacy. I'm terrified that a great many establishment Democrats, including the most powerful ones, don't get that. They think they can triangulate themselves between the Squad and the White House Occupant. But that's impossible. Every triangulation just gives The Occupant another opening, and he'll take it.
Like no other election in many decades, the next one is an all-out war for the soul of the country, and the world.
