(CNN) -- A modern-day David and Goliath story is unfolding in Washington state over whether you have the right to know what's in the food you purchase. The outcome will likely have national implications. What's at stake is I-522, the initiative that would mandate labeling food that is genetically modified. In support, you have a large grassroots movement that includes farmers and ranchers, fishermen, business owners and consumers. On the other side, you have a handful of large corporations such as Monsanto, Dupont and Dow that are fueling the food fight by spending millions of dollars to stop the people's right to know.
