The official measurement for that is now 80%. As in: HealthCare.gov goal is for 80% of users to be able to enroll for insurance. (With extra added periods of sub-optimal performance and the semi-regular crash)
Tomorrow, December 1, is the deadline. The real deadline is one approaching for those 5 to 8 million policyholders who had their policy cancelled because of ObamaCare. Each policy could represent several individuals, perhaps a family of three or four. If they do not, or are unable to purchase new policies by about December 15 they will start the new year without insurance. The Obama administration moved some deadline to December 23, but the reality is, it takes time to process applications. O thinks he can make a speech and change reality. He's finding he can not.
Twenty percent failure rate means between 1 million and 5 million people who previously had coverage on their own will now not have coverage because of ObamaCare.
ObamaCare is producing exactly opposite effects of what it was advertised to do. Less coverage, more expense and a terrific failure rate.
Close enough for government work. Remember to thank a Democrat.
