More proof he suffers from NPD. Narsos make outrageous statements all the time and never envision in their wildest dreams that they'll come back to haunt them. They have no moral compass anyway so statements from Trump about wanting to bang his own daughter, in his mind, is perfectly fair game. It's just that for the rest of us who do have a moral compass, there are consequences in the form of lost votes.
In the NPD's mind, all things they say are "great", "the best" and it's YOUR problem if you can't see it that way. This is their default mode. They have no other mode.
