Trumps retweets, now called retruths, were established long ago as a way Trump communicates with Q trained anons. Obviously, normies won't "get it", which is the point of this method of communication.

Plausible deniability. Trumps spent decades creating, maintaining and adjusting a public persona that convincingly masks his intelligence and lethality. In the 80s he openly talked and wrote about doing it and explaining why.
