Next week, the new state-based health insurance exchanges established under the Affordable Care Act, better known as Obamacare, will be open for business. Or rather — some of them will be sort of open for business, as the exchanges have been plagued by a series of technical glitches and delays. The Obama administration is now characterizing October 1st as the beginning of a “soft launch,” during which federal and state officials will work out various kinks. And though this might sound like just another bureaucratic foul-up, the success of the exchanges in these first few months will have enormous implications for the ultimate success of Obamacare.
