My problem is this, so far all the reporting I've seen are from intellectually dishonest people, framing it in the most intellectually dishonest way (the person who wrote it up for Refinery29 called it a rape allegation twice even though her own article never describes anything that could be defined as rape). That is a red flag. I don't know which 8 allegations you are speaking of, but my understanding is most of that is the creepy Uncle Joe stuff touching people's shoulders and making them uncomfortable stuff (which is a problem), lining up with this woman's previous allegation, and not stuff along the lines of her new allegation. So by bunching them all together you (Will) are potentially portraying a dishonest version of events that rounds them all up to this. I think when talking about these things precision is important. Anyway, he was one of my lowest ranked candidates among the Democrats, I didn't vote for him, but if we are going to move forward with someone else, I'd argue it cannot automatically be Sanders and we'd want to let the delegates decide.
And no, I don't think Biden would have the capability of suppressing this being reported by major outlets who have a proven track record of loving juicy stories that take down Democrats with or without regard to factuality.
