It’s time for the Affordable Care Act to join a long list of oxymorons. Why? Because rather like “military intelligence,” “cat proof,” “government organization,” and “simple calculus,” the law better known as Obamacare turns out to be an inherent contradiction. For a sizeable part of the population, anyway.

The ACA is just not affordable to a big chunk of those it was most meant to serve: The previously uninsured. In fact, many are worse off than before, according to a new study. That fact could also unravel part of the program’s foundation, which could be a problem for healthcare insurers.
