How can unelected judges limit the power of an elected official like the president? Two political scientists offer some answers in The Washington Post.

First, the public should broadly agree “about the basic legitimacy of the procedures used to review the powerful.” Second, the public needs “accurate information about the behavior of public officials.”

The authors say a free press should and does provide that information in various ways. That’s a good answer as far as it goes, but it does not go nearly far enough. Many other parts of our polity have the power and responsibility to provide information about government. To name a few: interest groups, bloggers, think tanks, professors, leakers, labor unions, trade associations, grassroots groups, and many others who might spring to mind with more reflection.

The media does not have a monopoly on informing the public. “The freedom of speech and of the press” belongs to all Americans. This diffusion of power seems especially valuable at a moment when the media lack credibility for so many Americans.
