Judging by the lack of comments on this article so far, not many people here follow this issue. The DC public schools are a microcosm of the whole ed reform movement, and an example of how difficult it can be to navigate the politics of reforming a corrupt system.
Rhee has done a lot to improve the efficiency of the district (in terms of getting books and supplies where needed, and using school resources wisely), but at the end of the day, her approach to reform (command and control vs. consensus building) is what will likely end her tenure early.
Right now, the mayor who backed her (Fenty) is in a tight race with a candidate who is exploiting people's distrust in a government that, for better or worse, acts based on what it believes is right for the people, not what the people believe is right for them.
Or, in the tl;dr edition:
When working within the confines of politics, you can get short bursts of successful but temporary reform, or you can be safe politically while accomplishing very little. There's gotta be another way.
