"Romney is ready to make the deep rollbacks in healthcare, education, social services, reproductive rights that will guarantee poverty, unemployment, overpopulation, disease, rioting -- all crucial elements in creating a nightmare zombie wasteland," he said . "But it's his commitment to unregulated corporate privilege that will nosedive this economy into true insolvency and chaos."
