Which liberal health policy experts have you been reading to get that impression of the Affordable Care Act?

I'm saying the law, taken on its merits, is not actually good by the standards liberals profess. I'm aware most liberals supported it (with some grumbling) but I think that's mainly because of Halo Effect/Affective Death Spiral. If George W. Bush had proposed this, I suspect liberals would have criticized it for locking us even deeper into the private insurance trap (giving corporations a captive market).
