I hope you will all agree that
increasing the stringency of voter identification requirements at the
polls may prevent some unlawful votes, but will also result in some
perfectly lawful votes not being cast, as voters, from various
causes, do not get the right identification in their hands by
election day.
What it seems, naively, should
determine the policy for identification stringency is minimizing the
sum of unlawful votes plus lawful votes that would otherwise have
been cast but were not as result of the stringency. Naive or not,
this is the voter identification policy test for which I will argue.
