I think part of the issue was that the audio was poorly mixed. This type of stuff happens at all kinds of events, but they typically isolate audio from the speaker only via lapel mic. You always mix in SOME crowd noise otherwise they don't seem to cheer. But it is a pretty dynamic operation with an operator raising the gain and lowering it as needed to get the desired effect. In this case the crowd noise was as loud as the speaker and as a result they seemed to shout over him.
