Romney argues that the public school system is broken and in desperate need of new ideas and new energy from the private sector. He is clear about whom he believes is to blame : A campaign policy paper calls public education “an antiquated system controlled to a disturbing degree by the unions representing teachers .” Teachers unions, predictably, have rallied to the Democratic president. They dislike some of his policies, such as his push to rate teachers largely by their students’ progress on standardized tests. Still, they are expected to spend millions supporting his campaign .
