I was on the floor at the time, and I saw these party leaders chairing the convention simply ignore points of order and objections. They also ruled that the Ayes had won a voice vote when the Noes pretty clearly shouted louder. It’s hard to get more undemocratic than simply making up the results of a floor vote.
Well, the video above helps explain what was going on. The teleprompter (see at the 2-minute mark) reads “the Ayes have it.” So, rather than describing what happened, the chairs just read their script.
