Herman Schwartz for Reuters Opinion:

Defenders of photo ID laws regularly cite public opinion polls that show widespread support for their arguments. Yet these polls reveal no such support, and they prove nothing about this new restrictive legislation because the polls’ questions cover a far broader range of IDs than the actual laws accept as proof of identity. Many of the new laws do not accept a college student ID, for example, or an out-of-state driver’s license; but the polls drawing favorable responses encompass such IDs. As always, the devil is in the details.

Important point.
