Without actually discussing what improvements would be in place, the 48% are largely irrelevant, and without saying what the alternative bill would be, the 12% are also (less) irrelevant.
The 48% are not irrelevant if the Republicans try to repeal Obamacare and don't replace it with something that preserves most of what people like such as guaranteed issue. And you can't preserve guaranteed issue without basically preserving Obamacare. Or at least the part that is used to rile people up against it, the individual mandate.
