Every one of us has family backgrounds and connections that might be perceived as giving us bias.  And we all do have biases and preferences.  For example, we have a PM who is from a family that has a socialist bias.  He has a brother that produced a laudatory documentary on Fidel Castro.  So what, Justin's a cool dude and so we vote for him.  This is not news except to those who like to pretend their biases do not affect their work.
