Robert Ellman at Intrepid Liberal provides a great discussion of lies and the marketplace. He then demonstrates how it applies to the Bush/Cheney administration, conservatism and the voters. Conservatism is nothing more than a set of easy-to-accept lies.
When conservatism fails and the incumbents who were elected as conservatives by conseratives, the failure of the ideology is then used to prove that the incumbents are NOT conservatives. They can't be. Conservatism as an ideology is perfect. The only failures are caused by indivuduals who fake being conservatives by are proven by their failures that they are NOT conservatives.
See? Conservatism (like Communism) is a perfect ideology. All failures are those of individuals to properly apply it, or to be less than totally resolute in applying it. As conservative prescriptions fail, the solution is to apply more energy to adopt those conservative prescriptions, because conservatism is perfect and cannot fail.
