I don't think you even understand what you're quoting. In the first place, the press release says that charter schools that take those steps tend to do better than charter schools that do not. That's different than saying those schools do better than their public school counterparts. As to why I'm "scared," that should be pretty obvious. Charter schools have already had a pretty broad adoption, and haven't worked out that well. There's not really anything else to say until you finally address this point and quit trying to make some weird abstract argument about Republicans and President Obama. I don't care. If the evidence suggests it doesn't work, I'm not eager to keep doing it. Period.
