Will Kamala say "middle class" during DC rally on Oct 29?

Kamala Harris has scheduled a rally on October 29 in Washington DC. (see: https://events.democrats.org/event/734570/). This market will resolve to "Yes" if Harris says "middle class" 5 or more times during their appearance at this event. Otherwise, the market will resolve to "No". Any usage of the term regardless of context will count toward the resolution of this market. Pluralization/possessive of the term will count toward the resolution of this market, however other forms will NOT count. If this candidate does not appear at this event, or if the event is otherwise cancelled or delayed beyond October 29, this market will resolve to "No". The resolution source will be the video of the speech.
