As we learned in California and Washington (states that narrowly lost GMO labeling initiatives despite being massively outspent) every debate draws more attention to the issue and weakens Big Biotech's undue influence over our food supply.
The junk food lobby's "federal solution" is to make it illegal for states to pass laws requiring GMO labeling. Period. End of story. This is not the way preemption is supposed to work.
Not sure exactly what genetically modified or engineered foods are? Well, fasten your seat belt folks, 'cause it's a bumpy ride.
