Obamacare isn't perfect but more importantly it is not sustainable.  It does nothing to constrain the runaway cost of medical care which left unchecked will bankrupt any medical plan to provide broad or universal coverage.  The Republican plan does not address the cost factor either and is thus destined to the same ultimate failure as the ACA.  We should nationalize medical care or at least establish a single-payer system with iron-clad cost control.  Only then can we realistically hope to provide lasting broad and high quality medical care.
