Comment: This is from a second semester course at Trump University: Trump Maxim XV:  Never accept blame for your failures.  Always be prepared to blame others for your shortcomings.  As a corollary, never apologize for any statement or action.  Remember: It is never your fault.

However, as a critique, if Trump had actually prevailed during the debate, he would be boasting to no end, so the need to invoke the above Maxim, indicates that he knows he made an ass and a fool of himself.
