One frustrating feature of the endless debates over the Affordable Care Act is that the positions of Obamacare opponents often turn out to be unfalsifiable articles of faith. I think it's helpful to think back to November and December, when healthcare.gov wasn't working and the enrollment situation looked dire. If that had continued — if the worst predictions of Obamacare opponents had come true — the law would have faced a real existential crisis going forward. But that's not what happened. The number of people without insurance is going down. Enrollment met, or surpassed projections. And in the face of these events, the Obamacare opponents who predicted that the law was doomed to a train wreck — certain to collapse on its own, leaving its foes to bathe in the political sunshine of a nation's anger — well, they have adjusted their position...not at all.
