Should "genetically modified" be on food labels, where it occurs?

      Genetically modified foods; should that feature be delineated upon labels, where such occurs? That question was defeated in a recent referendum in California; but it is being tested again now in Washington State. There, a rather heated "battle is being waged, with the Economist magazine of Nov. 8, stating that it is the second most expensive campaign in state history. The median contribution to the "yes" side is just $25,  but its ads are just as slick as the other side, the magazine says.
     The suggestion is that if such referendum is passed in Washington, other states will want to adopt similar laws - which would cause the federal government to become involved, to overcome the patchwork of rules which otherwise would occur. There certainly are different views about this question - but one will just have to wait  to see what democratic decision prevails; - a proper way to determine appropriate directions, it seems, to this writer.
