That is the final measure. In moments when the country looks up for orientation, Trump does not steady the room. He destabilizes it. He does not merely break norms; he erodes the conditions that make shared meaning possible. Where Reiner built a national cultural space—worlds we could all inhabit together—Trump dissolves it. He takes the scaffolding we’ve constructed and sets it on fire.
