Greg Sargent: “Stephen Miller has a theory about this political moment. As President Trump expands his lawbreaking and dictatorial rule, the powerful MAGA disinformation apparatus—at Miller’s direction—is supercharging public attention to the debate over Trump’s conduct in a way that’s designed to deeply polarize it.”“That will force Americans to take a side in that standoff, Miller clearly believes, driving them to embrace authoritarian rule, though perhaps without understanding it in exactly those terms.”“Do Democratic leaders broadly have their own theory about this moment? It’s unclear. But here’s what we can divine right now: Governors J.B. Pritzker of Illinois and Gavin Newsom of California do have one.”
