I try to make a habit of going back to op-eds and columns after a few years to see how they stood up (for instance this one does, I think this one does, this one I’m not sure). Recently Richard Whitmire reminded me of an October 2009 op-ed we wrote for the Wall Street Journal about the changing media climate facing the teachers unions.  We revisit it today in a RealClearEducation commentary pegged to the California state education chief race.
