ACA was nothing close to it because our voters don't allow us to get closer than that, as far as I can tell. I don't think people actually oppose universal healthcare, they just oppose the worst case scenario of its implementation, or some bastardized version of it, that is constantly emphasized by the politically/socially/economically powerful people on their side of politics. Some people even oppose it simply because it is associated with the other side of politics - that's frankly all it takes sometimes for an issue to be a non-starter.
