My column today at Newsworks WHYY asks why Gov. Christie, after a relatively peaceful interlude with NJEA top brass, has gone pugilistic again:

To those who follow New Jersey’s education politics — particularly the fraught relationship between Gov. Chris Christie and NJEA, NJ’s primary teacher union — the past six months have been as bucolic as a Norman Rockwell painting… Now suddenly, after months of apparent entente, Gov. Christie appeared last week in Jersey City at a school choice summit and had nothing but disdain for his erstwhile comrades.

Did our Governor have a temper tantrum? Did he go off-script? Did he forget his happy pills? How’d we go from Norman Rockwell to Edvard Munch’s “Scream?” Why did he revert back to the bad old days of deriding union officials?
