[WS:] This violates their 501c3 status which explicitly prohibits such endorsements and thus their tax exemption. If this can be substantiated, petitioning the IRS to revoke their tax exempt status may be worth a trial.
Another point - Ravitch argues that while public schools have to accept everyone, charters can not only pick and choose who to accept, but they can also expel anyone they want. So if there are any differences in aggregate test scores, they are most likely due to this selection bias. It is very difficult to control for it, because conventional controls such as socio-economic status do not capture factors that make a difference in educational attainment, such as motivation, parental upbringing, history of abuse, stability etc. These factors are really difficult to measure and thus control for..
As I see, the best way to attack school privatizers is to pull a Michael Moore on them - pay no attention to their sleek power point charts and graphs, but rather ridicule people who present them and undermine their credibility. For every lie you debunk, they will produce ten new ones, but they have no defense against ridicule. I generally eschew ad hominems, but if you face the corporate noise machine they are justifiable, as there is no other way to go short of actually silencing them.
