(Guest post by Greg Forster)
This morning, Pajamas Media carries my column on the results of the new Milwaukee studies released last week by the School Choice Demonstration Project:
It’s bad enough that everyone seems to be ignoring the program’s positive impact on public schools. About four-fifths of the students are still in public schools. Why look only at the results for the voucher students, only one-fifth of the total? If you had a medical treatment that would help four-fifths of all patients suffering from some horrible disease — and what else can you call the present state of our education system but a horrible disease? — that would be considered a fantastic result.
But it gets worse. These results don’t just show that the program improves education for students in public schools. They also indicate that the program improves education for the students who are using vouchers.

A quick update: in my column, I wrote “the usual suspects are misleadingly spinning the study as proof that vouchers don’t work, and the media is buying the spin.”
A commenter responds: “The media aren’t so much buying it as selling it.”
Touche.
