The problem with the ACA was that it had to make a lot of compromises to get it through with support by Republicans. While the ACA was initially very unpopular, it’s become more popular in time (if you discount rebranding efforts like Kentucky Connect being the name of the ACA marketplace there… Then Kentucky politicians calling ACA broken but Connect good causing Connect to be popular but ACA not in that state).
It was a good effort at getting the foot in the door for universal Healthcare one day, imo.
