So... if we believe the admin's 8 million signups figure (and why anyone would believe these liars is beyond me), then here's how it breaks out:

6 million previously insured

2 million (of the 47 million) uninsured

Or to put it another way:

Obamacare, which had as one of its main goals to insure the uninsured, has a 4% success rate.

And this, with the heavy handed approach of every citizen being required by Federal law to have signed up for insurance by April 1, 2014.

Seem like all Obamacare has done is create 45 million new lawbreakers out there and waste billions of taxpayer dollars.
