Woefully uneducated and uninformed.  The explanation was that most people knew what Obamacare is, but didn't have a clue what the Affordable Care Act is.  Ultimately, there is a vast swath of the population that is ignorant and seems to revel in that ignorance.  My previous career was in factories and I would see it there, most of those guys would listen to their media of choice, usually one of the AM talk stations and just be all about what the screaming talking head would tell them to think.  Since they screamed about Obamacare, that was the boogeyman, but The Affordable Care Act, well, that isn't that socialist Obamacare, so they didn't mind it in the slightest.
