Pennsylvania governor Tom Wolf has taken a step to fulfill a promise he made during his campaign. He just established a four-person unit within the state Department of Education to oversee the state's charter schools, which are publicly funded but privately operated.

Billionaire Rupert Murdoch, who has given money to one of the organizations pouring money into Massachusetts to add more charter schools, once told reporters, “When it comes to K through 12 education, we see a $500 billion sector in the U.S. alone.”

Wall Street's push for unregulated charter schools was blocked in Nashville. Will the same thing happen in Massachusetts in November?
