At the epicenter of the storm is political resistance. Some liberals and almost all conservatives are succumbing to objections to testing, educators' pleas for relief, and accusations that Common Core, while a voluntary action by the states, is a Trojan horse for federal encroachment. They cite the financial incentives and other sweeteners from the Obama administration to garner states' support. There is also an "if Obama's for it, we're against it" factor among conservatives. The tea party, according to a Washington Post front page story, is "mobilizing against Common Core education overhaul." Grassroots opposition is sprouting and succeeding in several states.
