The GOP is doing whatever it can to defund ACA but that will not work. The real battle is over the effectiveness its implementation. Paul Krugman argues that celebrity supporters of ACA, using twitter to reach their huge audiences, will defeat the efforts of Murdoch's propaganda machine to keep young people, who do not have access to employer provided insurance, from signing up at the exchanges.
I do not buy Krugman's argument. It is up to the administration to make sure that the public understands how to use the exchanges that are being set up in the states. The feedback that I get suggests that propaganda machine has been more effective in disinformation than the administration has been in informing the public. It needs to step up its efforts by an order of magnitude.
