Alexander Keyssar, a professor of history and social policy at Harvard, writes that a survey of world events over the last 20 or 100 years shows that democracies are fragile and democratic institutions can be undermined from within. He points out that the wave to restrict voting, including strict photo ID requirements, over the last few years is part of a much longer history of both parties rejecting democratic values in favor of partisan advantage. He asks us to be profoundly skeptical of laws that impede the exercise of what Lyndon B. Johnson called "the basic right, without which all others are meaningless." See his New York Times article giving a brief history of trends to both restrict and expand the vote: The Strange Career of Voter Suppression.
