I think this is the last of the accusers. If there had been any sexual stuff with a minor going on, that would have been sniffed out and put front and center. They put their best accuser forward (which is saying very little for these accusations), then tried to bootstrap other accusers to create a "where there's smoke there's fire" smokescreen, with which they have sought to (a) sink BK's nomination, or barring that (b) bog down the proceedings, or barring that (c) make the GOP look bad for the mid-terms.
From the very beginning, when Feinstein sent Ford's letter to the FBI 2 weeks ago, this has been a deliberate and orchestrated attempt by the Dems to sink or at least delay the nomination. The accusations were rolled out after BK's hearings were over to exact maximum damage to the nominee while providing minimal opportunity (a) to actually investigate/verify/corroborate the stories and look into the backgrounds of the accusers and (b) for the nominee to respond.
See through #MeToo, If she's a deceiver, don't #IBelieveHer.
