"[The ACA] sought a template for insurance rules, benefits and other structural features that would be the same from Vermont to Texas and Florida to Alaska. That was unwise. The continuous political warfare since the enactment of the legislation reflects the fact that different parts of the country have very different views of how health care should be organized.... The solution to these conflicts over engineering is to allow different structures to be adopted.... Different approaches also permit regional diversity within the broad bounds of national values and goals.... Amending the ACA to unleash federalism and permit states much greater flexibility to innovate is the way to achieve such a truly American health system."
