Regarding the defeat of GMO Labeling Proposition 37 in California in November of 2012, Common Dreams says this:
Opposition of Proposition 37 was spearheaded by large agribusiness and chemical companies—such as Monsanto and Dow—and big food manufacturers—including PepsiCo, Nestle, and Conagra—who dumped more than $45 million into the fight. Monsanto, a leading maker of genetically engineered seeds, contributed $8.1 million alone against the measure which would have required labeling on genetically modified food.

Recently, the apparent illegal activities of the Grocery Manufacturers Association in Washington State were uncovered, i.e., “the Grocery Manufacturers Association got caught red-handed violating Washington state fair election laws by running a money laundering slush fund designed to conceal the identities of food companies giving money to block I-522,” as Mike Adams points out.
