Consider that your opinion on what is "universally hated" is mostly shaped by the sources of information that you consume. Yours happens to be wrong. Overall the country views ObamaCare ~50% favorably, with some specific parts close to 90% approval.
> Following Republican efforts to repeal the Affordable Care Act (ACA) in the summer of 2017, KFF Health Tracking Polls have found a slight uptick in overall favorability towards the 2010 health care law. The most recent KFF Tracking Poll shows over half of the public (52%) hold favorable opinions of the ACA while about four in ten (41%) hold a negative opinion of the law. [1]
> Some 55% of Americans support the ACA, a record high since the law went into effect a decade ago, according to a recent report by the Kaiser Family Foundation, while 37% of the 130,000 respondents in the nationally representative poll hold unfavorable views. [2]
> But the election of Donald Trump and efforts by Republicans to repeal the ACA have boosted the law’s popularity. Since November 2016, on average, 49.4% of the public has had a positive view of the law, compared with 41.6% who view it unfavorably. [3]
