To a degree, I don't see the pathway for either to approach the topic any differently without major consequences. As has been discussed, this entire problem is one of intersectionality; it's victims vs. victims, and when that happens, nobody wins. To come out in strong support of the accuser is, in a political landscape as inflamed as this one, to come out swinging against the best chance to defeat Trump. If Biden loses against Trump, how would one avoid the suggestion that his chances were impaired artificially by those who should have been the most reliable allies to be enemies when all is said and done? 2016 -- not a thing anyone wants to re-litigate, I know -- is still a mess one way or another without the needed retrospective and analysis that could help the party better understand itself and its priorities, but as of right now, were Warren or Sanders to come out in swift support of a victim in need of said support, they would almost certainly be blamed for a loss should it happen, even if data doesn't bear it out.
I hope that the party understands that as awful as Trump is and as unfortunate as these circumstances are, the decisions powerful people make that undermine victims will be remembered -- whoever those victims are -- and without honesty and integrity on their side as they make those decisions, well, they will be haunted by that. As long as this party wants to be the one guided by a moral compass, it will be strikingly clear any time they choose to abandon it as they wrestle with these issues.
