This is no longer about policy regarding the health and healthcare of citizens.  It is about Trump's ego, and the GOP's dogmatic pursuit of undoing something that's basically good, in principal (but not nearly perfect) done by Obama.  The stakes in this little ego-fest are health, safety and welfare of individuals who might be in need of meaningful health insurance coverage to deal with the realities of being a human being - ill health that is treatable, fixable and curable by modern medicine.  
This may well end up being the most cynical moment in American history since the debates over slavery and/or women's suffrage.
Understand this:  Definitionally, I think healthcare is the act of caring for health.  Healthcare insurance is therefore a mechanism by which people may look to insurance coverage to cover healthcare costs.  The GOP is knowingly trying to enact a law that will have the effect of (I think actually designed to) lessen(ing) American Citizens' access to healthcare.  Evil.
