Grimes also described it as a "difficult, challenging book", saying "you can almost hear the pointer hit the blackboard as he works his way rigorously through each argument and sub-arguments A, B and C, before proceeding to the next step.
Because there is a much easier and much more powerful argument to make, if you set the voter ID sub-argument to the side for a moment.
