Local supporters of D.C. Public Schools Chancellor Michelle Rhee have grown more organized in recent weeks, as her attempts at reform have come under sharper attack from union officials and members of the city council.

“I’ve never gotten more e-mails from people all over the city asking what they can do to help,” said Anne Martin, executive director of D.C. School Reform Now, an advocacy group in favor of systemwide changes such as entrusting principals with more power to hire and fire.
