One thing about the Patient Protection and Affordable Care Act (PPACA) is that it's a huge law. It does all sorts of things.
When people say, "I want to repeal PPACA! All of it!", I doubt many of them are talking about the tanning salon or Medicare reimbursement innovation provisions, for example.

Whether accountable care organizations (ACOs) are the best thing since chocolate or the worst thing someone invented the concept of running out of chocolate, few civilians have the same level of hatred toward ACOs that they have toward the PPACA public exchange system, exchange plans, and the idea that some people have to pay for health coverage or else pay "an amount" to the federal government.
I think that even many people who loathe PPACA, and are well-informed enough to know what the words mean, like the idea of insurers being able to sell health coverage to responsible but unlucky sick people at a reasonable cost, and to get away from the practice of trying to kick people with cancer out of plans because they failed to include information about treatment for acne and head colds in coverage applications.
