Donald trump is constantly looking for approval because he never experienced it in his childhood. He's a damaged human being and we all have to pay for it.
His father's persona was split between his sons. Fred jr. received intelligence, Donald ruthlessness.
Fred jr. got demolished by his father's cruelty. Donald alligned his own cruelty with that of Fred Trump to get some acknowledgement and affection.
Without the constitution we would already be in Trumpland.
