This is a fundamental misunderstanding of how the political structure of the US works. The individual States are responsible for regulating healthcare, the Federal government has little jurisdiction as a Constitutional matter.

There are many single-party States that nonetheless have broken healthcare systems. You can’t legitimately blame the intransigence of any political party in those States, they control their own outcomes. I live in a single-party State (Democrat) and the systemic incompetence and corruption in healthcare is evident without any Republicans in sight.

Americans have very little contact with Federal law. The legal environment they live in is set by the States, by design. If you don’t like the laws where you live, or the competency with which they are executed, that is on the State.
