Alexander Keyssar fears voter suppression:
The current wave of procedural restrictions on voting, including strict photo ID requirements, ought to be understood as the latest chapter in a not always uplifting story: Americans of both parties have sometimes rejected democratic values or preferred partisan advantage to fair democratic processes.

Johnson called "the basic right, without which all others are meaningless." More is at stake here than the outcome of the 2012 election.
