From the piece:
If Obamacare had been in place, back when the steelworker lost his job, would he have been able to get insurance for his wife? We finally have an answer: Probably not. It turns out they would have fallen into a group of people whom Obamacare will not be able to help. The group is relatively small, particularly relative to the tens of millions of Americans that the law will help. But their situation is a reminder that plenty of unfinished business will remain after January 2014, when most of Obamacare takes full effect.
