Here are a couple of good reads on the subject.
First, Reason's blog has a pretty good screed on the teachers union's big victory in the city.
Next, the weekend WaPost had a very interesting article on Mr. Fenty's loss. Lots of discussion of Mr. Fenty's being out of touch with the black "community", but also a pretty solid case for the view that the "community" sees the city education system NOT as a venue for educating its youth, but as a jobs program for its adults. You get what you pay for.
