I think you'll agree that there's a big difference between criticizing corporate culture run amok and not supporting small, mom-and-pop small business owners. Without going into who has said what, it would be a serious caricature of anyone's position to say that, because they have concerns about Romney's performance in big business, they must also be down on the farmers trying to eek out an honest living.
Whether you support Romney's performance or not, I think we need to be honest with ourselves and each other. Nobody really wins if we're all relying on exaggerated hyperbole and vast leaps in logic. That's true whichever side you come down on.
