You mean the video that shows Sanders supporters preventing speakers from talking — whether it be Clinton supporter like Barbara Boxer or “one of their own”? Yeah, that certainly makes it clear that there is a problem in the Democratic Party — but it’s NOT with “the establishment.”
You do realize that:
- the process followed rules — with respect to recognizing delegates — that were established back in 2012
- the results were confirmed by a committee that consisted of five Clinton supporters and five Sanders supporters — including a Sanders co-chair
- at the end of the day Clinton was awarded 20 out of 35 delegates (to Sanders 15). Given that she won the original caucus by 53% to 47% that’s not entirely unreasonable (while 18.5 to 16.5 would have been more “correct”).
Those are all facts you can look up.
