According to research by the Rudd Center for Food Policy and Obesity at Yale University, the declared politics of school districts is an excellent predictor of their school-nutrition policies. Democrats, which generally believe in the power of government to improve lives, institute policies for better nutrition. And Republicans, who generally believe in the primacy of the marketplace, put fewer strictures on what can be sold to schoolchildren.

So what do you think is the more important standard for school-food nutrition: children's health or corporate rights?
