In his appearance yesterday on Fox News, Obama said that “I’ve been very clear about the fact... that we should be experimenting with charter schools.” Actually, he hasn’t been very clear about that fact, at least during this campaign. (He was a well-known charter supporter during his Illinois Senate days.) His formal education proposal, for example, never mentions the concept. And it’s sure not a part of his stump speech. While he hasn’t kept his support a state secret (see here, for instance), to my knowledge this is the most high-profile mention he’s given to charter schools to date.
