I never thought Trump win, but I still stand by the assertion that he could have. It's October and likely things are completely imploding his campaign, but a month ago I would have bet he would've lost like McCain and Romney lost, not lost like Mondale or Dukakis lost. He still probably won't lose like Mondale or Dukakis.
If he'd run a real campaign, been a bit less lazy, hired people less incompetent and evil than the ones he hired,... well, he could have won. Probably not. But it was possible.
