Today’s Wall Street Journal on NYC Chancellor Joel Klein’s departure:

The school reform movement has gained momentum in recent years as more Democrats like Mr. Klein and Michelle Rhee in Washington, D.C., have taken up the task and spoken honestly about a system that serves the adults it employs, rather than the students it claims to serve but fails to teach. The unions believe they can prevail simply by waiting out the reformers. They’ll be right if others don’t continue the fight as tenaciously as Mr. Klein and Ms. Rhee.
