Senators Jeff Flake & John McCain   President George W Bush & Senator Bob Corker

You have THAT family member. Charming, well liked, the family member who has consistently helped other members of the family.  The family member is financially successful and wields considerable influence in the family.

This family member is manipulative, they have hurt many members of the family.  No one has challenged the family member because of their wealth and influence.

Anyone who challenges the family member risks expulsion and being shunned by other family members.  The abuse is well known and no one is exempt from the abuse and yet no one wants to fall out of favor with the family member
