He's kind of a reverse Hillary, in a way. Biden is taking the warning signs seriously and trying to do (almost) everything it takes to win, but it won't be enough because as a candidate he's just kind of doomed to lose, especially because of his age. Hillary, on the other hand, was practically guaranteed a victory had she just run an intelligent campaign using the exact same playbook Obama used against Romney, but instead she did nothing and made no attempt to respond to any issues or developments that damaged her or helped Trump.
