Trump can't be seen as the President right now. If you can't see that there are some serious military operations going on damn near every day I can't help you. He needs to be hidden to do the things that he's doing right now: clandestine military operations.
However, those military operations will come to an end, and when they do, the movie comes to an end. Hence 'Enjoy the show'.
IMO it serves two main functions: 1. fool the lower parts of DS into false sense of security, so the military operations in OP can be carried out. 2. Operation Wakeup the Normies via dismantling any credibility MSN has left.
