I always believed the opposite to be the case... I never believe polls that most Americans opposed the ACA. Rather, they opposed Obamacare. People were conditioned by the propaganda to dislike whatever Obama did. But as it turns out, they like Obamacare's pieces and parts -- prohibiting exclusion of people with pre-existing conditions, allowing dependents up to age 26 to remain on parents' policies, eliminating lifetime limits on coverage for catastrophic illnesses, expansion of Medicaid, even the individual mandate to purchase health insurance (originally a Republican idea), just like you have to have car insurance. They generally liked all these parts. The part they didn't like was the "Obama" part.
