From what I've read the victim decided not to speak out and somebody leaked her story anyway. I don't see any reason to doubt her and I think she is right, this won't affect the confirmation. I think Kavanaugh either doesn't remember the incident or does and is a giant douchebag, but not anything compared to the media who published the details of a sexual assault in nationwide press against the victim's wishes. Confirm Kavanaugh and try the press.
She took a polygraph and we are talking about something she brought up in therapy with her husband in 2012. I doubt she is lying.
