We still don't know how many people got health insurance due to Obamacare. Seven million registered but how many paid their first months premium and continued to pay their monthly premium after that, we don't know. Now, however, it looks like as many as one million of how ever many it was that got insurance under Obamacare, may have gotten the wrong subsidy. Subsidies are tied to income and it appears a lot of people reported the wrong income. Maybe some of them did not get all the subsidy to which the law entitled them, but a lot may have gotten too much subsidy. To read all about it, follow this link.
