At least two thirds of the 2.2M people who purchased health insurance from exchanges under Obamacare through December 28 already had coverage, preliminary surveys indicate.
In a McKinsey study, just 11% of people didn't have insurance previously. Affordability and technical problems were among the reasons why people didn't buy plans.
Around 48M Americans didn't have health insurance in 2012; Obamacare is expected to reduce that figure by 25M.
Meanwhile, the government is delaying yet another provision of the Affordable Care Act - one that prevents employers from offering better health benefits to senior management than to other staff. The reason is that tax officials haven't yet issued the regulations that companies need to abide by.
