It seemed like a no-brainer: changing the law to allow the federal government to buy food in Africa for Africans facing starvation instead of paying enormous sums to ship it from the American heartland, halfway around the world. Not only would the food get to the hungry in weeks instead of months, the government would save money and help African farmers at the same time. So why is this seemingly sensible, cost-effective proposal near death in Congress?
