When Donald Trump was publicly proven wrong yesterday by President Barack Obama releasing his long-form birth certificate (reiterating what we already know is true: He's a U.S. citizen), most people expected Trump to react with some variation of "I'm an idiot. I was wrong." Instead, Trump used the opportunity to praise himself.
"Today, I am very proud of myself," he said at a news conference. "... I feel I've accomplished something really, really important and I'm honored by it."
How does one make sense of this inexplicable behavior?
Jon Stewart explained it all very well last night on "The Daily Show": Saying he's "very proud" of himself is actually the worst thing Trump has the ability to say about himself. His self-confidence is so high that phrase is actually an insult.
