My favorite passage from the Charlotte Observer article referenced above:

John Dornan, executive director of the Raleigh-based advocacy group Public Schools of North Carolina, knew about that report. But he said Wednesday he was shocked to hear that CMS, long held up as a horror story of what could happen if Raleigh were to let schools resegregate, was outperforming Wake on many measures.

“Wow,” he said, when told about the report-card results. “Could it very well be that (CMS efforts) are paying dividends? It’s hard to think of another explanation.”

When the facts get in the way of ideology, expect surprise.
