I do wish Biden had been asked during the debate what role, if any, his family would play in his administration. Would he have replied: the same sort of roles as my predecessor has assigned to Ivanka, Don Jr., Eric, Jared Kushner or would he have excluded them? Would he promise to put his assets into a blind trust?
