In 1945, Congress passed the McCarran-Ferguson Act, a clear acknowledgment by the federal government that states are indeed the most appropriate regulators of health insurance. It was acknowledged that states are better able to understand their consumers' needs and concerns. It was determined that states are more responsive, more effective enforcers of consumer protections. As recently as last year, this fact was re-affirmed by the General Accounting Office. Wyoming has its own unique set of health care needs and concerns.
Every state does.
For example, despite our elevation, we don't need the mandate regarding skin cancer that Florida has on the books. My favorite illustration of just how crazy a nationalized system of health care mandates would be comes from my own time in the Wyoming Legislature. It's about a mandate that I voted for and still support today. So, we passed an any willing provider law that requires health plans to contract with any provider in Wyoming who's willing to do so. While that idea may sound strange to my ears in any other context, it was the right thing to do for Wyoming.
