Then there are the roughly three million people said to have signed up for private insurance. In mid-January, the Wall Street Journal reported that a relatively small percentage of the new sign-ups were previously uninsured Americans gaining coverage through Obamacare. The rest were people who were covered and lost that coverage in the market disruptions largely caused by Obamacare.

A McKinsey and Co. survey cited by the Journal found that just 11 percent of private insurance signups were people who previously had no coverage. Other surveys found that about one-quarter of new sign-ups were previously uninsured.

Whatever the precise number, it appears that a large majority of the activity in Obamacare private coverage sign-ups is essentially a churn operation: The system throws people out of their coverage, and then those people come to the system to sign up for new coverage, and that is reported as a gain for Obamacare.
