I think the Liar-In-Chief actually believes the wonder-self-ness of what he is saying this time. I've seen this happen to braggart tall tale tellers who only get worse.
From allo's dino dictionary--
delusional: a dipstick (whose elevator no longer goes all the way to the top) with a persistent false psychotic braggart's belief regarding the grandeur of the entitled self or the created candy mountains attributed to the glory of the whack-job self.
