Sally Kohn sums up Trump's performance this way:

Quote
Question after question, Trump said nothing. I mean, words came out of his mouth but they barely formed sentences and they definitely didn't form thoughts. He basically vomited fragments of nothingness all over Hillary Clinton and America. And like Clinton, we all just had to sit there — frustrated and annoyed.

What's especially depressing is that our media, let alone our democracy, seems ill-equipped to handle anything like Trump. Martha Raddatz and Anderson Cooper tried, but fact checking Trump doesn't work because Trump doesn't care about facts. In fact, he denies he's lying as he's lying and then, for extra audacity, accuses everyone else of being liars. I keep waiting for the ghost of George Orwell to show up on the debate stage and bite Trump on the ankles.

Donald Trump is a perverse man who is perverting not only our democracy but the very concept of truth. He tried to win the debate just like one wins a limbo contest — by lowering the bar. That should depress all of us.

You never change things by fighting the existing reality.
To change something, build a new model that makes the old model obsolete.
