I don’t think the Democrats did themselves any favors by not surfacing this thing for the past couple of months. Now it smacks of a desperate last-minute play.
I think they should interview the accuser but I doubt anything said will do much to change the position of the Handmaids cosplay society. I’m not sure what anybody can do at this point to establish the truth of what happened all those years ago. People will simply default to their established positions and “believe” who they wish to.
