The charter movement is dominated in the trenches by progressives, even when we've been represented on the national stage by conservatives.
I think that is accurate. I'm currently on a board trying to charter a school. We met today, and the entire board seemed liberal and progressive, as do most people working to improve our schools through charters. Are we being used? Maybe there is a middle ground where some businesses can profit with charter schools, some schools stay public, and ALL children can get a great public education.
