That's true but not very relevant ActBlue had $1 Billion at the beginning of August and will spend $1.5B. The bigger problem is energizing the blue voters. If this drags out into early voting time, they will be energized and they will vote. It would be better to resolve it before then. OTOH they can't simply dismiss the Ford allegation without a hearing because that will also be used by the other side.
Early voting has already started in some states. There was a posting on FR recently with some of the early voting start dates.
