The number of uninsured people in the United States has dropped by the millions thanks to the Patient Protection and Affordable Care Act of 2010.

Just how many depends on how you count and who’s counting. Whether the number is 9.7 million (according to the Gallup-Healthways Well-Being Index) or 16.4 million (according to the Obama administration), that’s still millions of people who have been able to get health insurance who didn’t have it before.

So, for all of the Republican rhetoric about repealing the law, they will have to deal with millions of people who would lose their coverage altogether.
