As centrist Republicans contemplated an Obamacare repeal-and-replace plan, the CBO warned that doing so would boost the number of uninsured by 22 million. That scared enough Republicans away to kill the bill. The intrepid Philip Klein at the Washington Examiner noticed that, buried in a footnote, was a stunning rebuke of those CBO forecasts. Turns out, the CBO’s forecasts off by a factor of six. The report says that the mandate repeal will result in only 1.5 million dropping out of the individual insurance market, and 1 million from employer plans, with Medicaid enrollment unaffected. These forecasting errors don’t even rise to the “good enough for government work” level. But they were good enough to get Obamacare on the books, and then keep it there.
