"The mix of sick and healthy customers has been worse than expected" only to complete idiots. It was clear from day 1 that the needed, healthy young people don't tend to earn much money so paying the income based penalty would be much cheaper than buying coverage.

But then folks who rely on liberal media for news never heard any critical coverage of anything Obama. Even
 the war protests fell silent for him. And he actually escalated to other countries.
