Disagree, I think you have your timeline mixed up.
The 2016 election occurred well after Occupy Wallstreet, and Bernie Sanders and the progressive wing in the democrats felt snubbed in 2016, which is why many of them stayed home.
I know this because I was one of them, and I will have to live with that decision for the rest of my life.
Edit: I am not realizing you might be referring to the 2008 primary election, I'm talking about the 2016 presidential election here and in my original comment. Contextually it (your response) makes sense based on the date of the video, so I get your point, but not what I was talking about.
