Common Core pushback

Looks like the Common Core just got an organized opposition.
A few things of note: it's a fairly conservative group of signatories (Worcester's own Roberta Schaefer is on there! Actually, so are the Thernstroms and John Silber...it's like a "Who's Who" of the 1990's Massachusetts Board of Ed! ). It largely is criticizes on national curriculum grounds; Hess notes potential parallels with the national curriculum battles of the 1990's.
