By the end of February,
3 million people had gotten Medicaid since Obamacare sign-ups started—and that's probably lowballing it:
In 46 states reporting both pre- and post-Obamacare data, enrollment in Medicaid and CHIP before October grew from about 58 million to 61 million, according to the Centers for Medicare and Medicaid Services.
"It is important to note that enrollment numbers reported today are underestimates of what the actual enrollment in February will ultimately be," a CMS fact sheet noted. That sheet noted that not all states have reported enrollment data, and "the data are preliminary and do not include most individuals who will later be found eligible for Medicaid effective in February."
Of course, the number would be much, much higher if some Republican-controlled states hadn't refused Medicaid expansion, denying 5.7 million people Medicaid eligibility
and subsidies for private insurance.
The Affordable Care Act is far from perfect, but damn, it means health coverage for a lot of Americans who had been uninsured, or paying more than they could afford for insurance that wouldn't have been there when they really needed it.
