We're told that we may get further information regarding what the Republican replacement for the Affordable Care Act may contain. I'm sure we'll be seeing plenty of views as to what's good about it, and what's not, but taking the long view, I think one thing is certain:
The real accomplishment of the Obama administration and the ACA that it legislated is not so much specific provisions, though of course it's good for all of us if more citizens obtain health insurance, and provisions like those involving pre-existing conditions and others are naturally very popular.
For me, taking the long view, I see the ACA's most important feature as having pushed the envelope to expand health care to the point that even (most) Republican pols can't do away with it. Oh, yes, they will try. After all, Republicans have fought tooth and nail since the Roosevelt era against the whole idea that government has a duty/mission to provide health care to all. But the ACA has moved the ball forward a couple of steps - its opponents are already finding they can't move it three steps back (perhaps one). And that's the definition of progress.
Democrats have become a bit sensitive about calling themselves "progressives," but I think it's a fine term, in part because it offers its mirror image - "regressive" - as the definition of what the Republican Party and its current standard-bearer represent. Over time, societies choose to progress rather than regress. I've always said the GOP efforts to put a negative spin on the ACA by dubbing it "Obamacare" would come back to haunt them. No matter what alterations they make now; it will remain a significant Obama legacy.
