Could a wording 'glitch' doom Obama's healthcare law?

When a federal appeals court ruled last month that a seemingly arcane wording flaw in the Affordable Care Act should invalidate a central part of the law, many of those who drafted the statute five years ago reacted with shock and anger. In 2009, they had spent months piecing together a compromise that sought to create a national system of subsidized insurance — but one run by the states. Now, they fear their work could be undone by what some call a "drafting error" and others portray as a political miscalculation.
