Janet Barresi, state superintendent in Oklahoma, was defeated in the Republican primary by Joy Hofmeister, a former teacher and state school board member. Barresi was a member of Jeb Bush’s Chiefs for Change (which dropped from seven to six with Barresi’s defeat). . She supported Jeb’s A-F grading system for schools, which Hofmeister opposed. Like Jeb, Barresi supported Common Core until Oklahoma dropped (h/t to Mercedes Schneider for the correction); Joy Hofmeister does not.
