OK, I get it.   If he lies, it doesn't really count because his previous statement wasn't real....it was "off the cuff"..."just a joke" or whatever.  His lies about simple demonstrable facts....like the size of inauguration crowds..don't count either.. If he "actually believes" those photos are "doctored" and "faked" he's not really lying.  George Washington's "I cannot tell a lie....I chopped down the cherry tree" is a wonderful myth.  Donald Trump's statement must be "I cannot tell a lie, because the lies I tell aren't really lies in my mind, so they don't count."  Please see the definition of a pathological liar which I have posted. Using your description of Mr. Trump, he certainly qualifies.   Without intending to, I think you're getting closer and closer to recognizing the extent of Mr. Trump's psychological problems.   congratulations on your progress... Gary crum
