There’s no longer a (close) election for which to pretend. Not that he was pretending much before, having enacted the fascist anti-immigration bill via executive order that Congress refused to (so as to avoid giving him credit).
IDK the difference is that Trump Jr. is close to imperial power, whereas that (pre-)teen was not. Politics doesn’t care about the powerless, and (especially with overwhelming fascist influence) will trample them like ants.
