Now I get that this source is mainly speculative, and dependent on eyewitness account, but with how everything took place in 2015-2016, I fully see the above being a completely valid happening.
I don’t have any specific memories or sources on hand since it was like 8 years ago. So by all means take this with a fairly large grain of salt.
But I’m pretty sure it had something to do with the DNC actively pushing for Hillary and denying Bernie the same resources and privileges guaranteed to other candidates. Like there was a substabtial amount of money that was intended to go to the nominee, but Hillary got it well before the primaries. Also there were the emails that got leaked from DNC execs who were very openly against Bernie and discussing ways to debase him or otherwise get support for Hillary to beat him despite their role as neutral orchestrators in the primaries.
We don’t know everything. Really just the email leaks and a few reports here or there. But judging by what we do have it paints a pretty damning picture for what we don’t have.
It was a lot of stuff. I’m still mad about it. Of the top of my head: they very quickly got rid of polling locations in places he was polling high in multiple states after they realized he was doing well and people were standing in line to vote for over 8 hours, they lied about stupid shit like the fake chair throwing thing they made up to make it sound like anyone on his side were violent, they ignored the caucus rules in Nevada where he clearly won based on video at the time, there was more, but it’s been a long time and this are just a few examples that cross my mind on occasion
There have been a handful of times where I wish I had just written it down because I see the “I never saw/ heard about this” line often enough.
The DNC admitted collision in court, what else do you need lol
