I am no fan of Shuckster and never have been. I was outraged about his pardon insanity even before he became a Presidential candidate.
With that said, it’s not fair to blame him for a parole unless he took a personal interest in the case somehow.
He deserves all the scorn and ridicule he is getting for the clemency he issued Clemmons but parole (and often the subsequent supervision after release) is badly broken in every state that I am aware of.
Who chooses who sits on the parole boards? Governor?
