It doesn't matter what it sounds like from the middle of the sanders section. That's totally irrelevant. What matters is the judgement of the chair, who by the rules has the ability to judge whether it is close enough.
Yes, the credentials committee was evenly split between Sanders and Clinton. Not very hard to figure out, and another fact that the video decided to conveniently omit.

The fact that it's a video summary doesn't excuse it from not mentioning the chair throwing and death threats, which appeared all over the news. He cited other news articles in the video, why not the ones about the rioting? The death threats were a NYT headline, and "Thrown Chairs" was the first sentence. It was also reported in AP, WP, and other places but the video guy doesn't think it's worth even mentioning? And he does think it's worth quoting some comments from a Daily Caller article? It's a total joke.
Sanders had more people disqualified because Sanders people unregistered as Dems to spite the party. "According to the video" is meaningless because the video is Sanders/Daily Caller propaganda. The rules were followed, and Bernie lost. Then his supporters got upset and made sexist chants and death threats and threw chairs.
