Matt Ladner has a good commentary this morning on NRO, pointing out that the Obama administration must have known the positive results of the latest DC voucher study that it finally released last Friday, well before Democrats in Congress voted to phase-out funding for the program after the 2009-10 school year.

As I noted immediately after the study’s release, this program is achieving better results at a QUARTER the cost of DC public education: $6,620/pupil vs. $26,555/pupil.

But education secretary Arne Duncan and president Obama watched it die without mentioning these findings. 

Perhaps if Duncan were secretary of defense he might worry that journalists would investigate just when his department received the results of this study, publicly shaming him. But he isn’t, and so he won’t. In education, we have precious few investigative journalists, and even smoking guns like these arouse little interest.
