After three counties in California successfully passed bans on the planting of genetically modified crops, the GM seedmakers got smart. They've started pressuring state legislatures to pass pre-emptive laws that prevent localities from enacting their own bans. If you can't corrupt the locals, then move to the states. I think the reason the companies don't move to the national level is that this would provoke a huge national fight that they might not win. Better to work state by state with measures that are easier to hide from the public. After all, how many of us know what major bills are pending in our state legislatures?
