The department also said it believes that most of the new enrollment in Obamacare plans for 2015 "is likely to come from the ranks of the uninsured."  The department's analysis projects there will be about three to four previously uninsured new enrollee for each new enrollee who comes from people who had had individual plans sold off the Obamacare exchanges.  The downward revised enrolled projections were met with disdain from a leading Congressional Republican, whose party has relentlessly criticized Obamacare for years.  "After years of broken promises and a painfully flawed launch, the administration is again trying to rewrite its definition of success for the president's signature law on the eve of Saturday's second enrollment," said House Energy and Commerce Committee vice-chairman Marsha Blackburn, R-Tenn "Last year, while cancellation notices were outnumbering new enrollments, the administration completely abandoned enrollment as a measure of success."  "No matter how you dress it up, bad policy is bad policy," said Blackburn. "Before administration officials takeout the Champagne again to celebrate its now downgraded measure of enrollment success, it needs to once and for all be transparent with the American people about the reality of this law."  HealthCare.gov and the 15 Obamacare exchanges run by the District of Columbia and individual states first began operations in October 2014. After two months of disastrously low enrollment as a result of technical problems on HealthCare.gov, enrollment strongly picked up in the first quarter of 2014.  By the close of open enrollment last April, there were about 8.1 million people enrolled in Obamacare plans.

Most current Obamacare enrollees will be automatically re-enrolled in their current plans, unless they opt for another plan.
The Obama administration says less than 10 million people are likely to sign up for Obamacare by 2015, much less than 13 million projected earlier.
