This article looks at plans being discussed around how to save the ACA from the GOP axe. I think the broad strategy of focusing on personal stories is a good one — people respond better to that than to broad stats. (Expect, though, some massive attacks from some quarters on anyone who is put forward as part of that narrative — threats, doxxing, and outright slander that will become "believed" because all the usual suspects repeat it).
I also think being ready to tackle a repeal-and-delay tactic ("We're going to repeal all this, but it won't go into effect for a couple of years while we figure out what the hell we're doing to replace it") is also wise. The GOP have always talked about the dangers of "regulatory uncertainty" and how that hampers businesses from being able to plan — leaving the whole health insurance industry and process and future up in the air is not going to help any business (or citizen) plan for their future.
The ACA is flawed legislation, but it needs to be fixed (like any other complex program), not just thrown out without any provision for how to address the problems it was rightfully focused on. In a sane world, Congress would have spent the last several years doing just that, seeing what worked and what didn't and patching the thing after its initial release. Instead, today, we have the current situation, and the debate has become less about how to make sure that people get the important medical treatment they need and more about one side trying to finally "win" over the other.
