Nah, when a parent is narcissistic they often triangulate.  They have their "golden child" and then they have their "scapegoat".  Beau being older was the golden child.  This was demonstrated pretty well at the debate.  He didn't treat those kids the same. Hunter knows he would never measure up to Beau. I have also witnessed families where sadly one child is badly abused and the other(s) can do no wrong.  Seems like this might be the case with the Biden family.
