I don’t actually see this as much of a realignment. It’s just the endgame of the Southern Strategy, coming to a head. Today’s Red America and Blue America isn’t really all that different than yesterday’s Gray America and Blue America. If White Identity Politics loses for a third time, if they’re no longer popular enough to be at the center of a national coalition, we can certainly hope for a more productive political realignment in the future, along, say, policy lines.
As for anti-reality, there’s a method to the madness: You call President Obama certain bad words, and you get pilloried, but you suggest maybe he has exotic origins that make him unlike the rest of us real Americans, and you get elected. Repeating patently and provably untrue things is often just a smokescreen, a way to assert group membership without betraying anything more malignant than stupidity. Trump made liberals laugh by denying reality, but he made white supremacists vote – and that was the goal.
