Palatable, surely you realize that only stupid people claim they are smart, right? Furthermore, only a catastrophically stupid and deeply insecure person would claim things like:

"Sorry losers and haters, but my I.Q. is one of the highest -and you all know it! Please don't feel so stupid or insecure,it's not your fault" (May 8, 2013)

Used occasionally such statements imply the speaker actually believes these they are the loser, hater, low-IQ, stupid and insecure one, not whomever they are attacking.  

Trump makes such claims ALL THE TIME and has been doing so for decades.  Chew on the implications of that for a bit.
