This has absolutely nothing to do with the "left". This has everything to do with the future of America's children. Fatty foods and illicit drugs have nothing in common and to make such a link, shows a shallow understanding of the serious issue of drug abuse in America.
They are linked. If it can be deemed acceptable for the federal government to overstep its constitutional bounds and ban illicit drugs, how much of a stretch is it to assume they can and will do the same thing with fatty foods? Heart disease is supposedly one of the biggest killers in America, more deadly than illicit drugs. Doing something for "the future of America's children" is certainly noble but the war on drugs—to the extent that it federalizes what should be a state and local issue—is unconstitutional. To think that it isn't shows a shallow understanding of the serious issue of constitution abuse in America.
