I think the Dems know she lied but they have to pretend to believe her. It's the only way they can justify an impeachment. The courts are the main avenue Dems use to force their agenda on the American people so they have to maintain a majority of leftist activists on the SC and Kavanaugh ruins everything for them. It could have been anybody and they would have done this.Democrats still believe these accusations. In fact they intend to impeach Kavanaugh for denying them.
