 I was once pretty confident that Donald Trump would not be the nominee in 2016, and I was shown to be wrong there, so I'm kind of out of the prediction business. But I will say that there's a really compelling reason to believe that Biden will stick it out. He does not like to be pushed around. He has a sense of his own personal narrative, suggests that when the media says you're not good enough, that doesn't mean you're not, and you want to show them.
