If insanity is defined as doing the same thing over and over and expecting a different result, it's tempting to observe that congressional Republicans have gone stark, raving mad. My own GOP congressman Rep. Tim Griffin recently boasted in a column about having "voted more than 30 times to repeal all or parts of Obamacare."Only in politics does somebody expect praise for sheer futility.In the column, Griffin quoted the Washington Examiner, one of those tycoon-funded right-wing propaganda publications reporting that "cost estimates from 17 of the nation's largest insurance companies indicate that health insurance premiums will grow an average of 100 percent under Obamacare, and that some will soar more than 400 percent."Yeah, well the results are starting to come in. In California and New York, the nation's two most populous states, which have set up health care exchanges, premiums have dropped sharply below Congressional Budget Office projections.According to the New York Times, "State insurance regulators say they have approved rates for 2014 that are at least 50 percent lower on average than those currently available in New York.
