If you bother to read that story, the urgent care could not treat him (probably because urgent care is not setup for Covid-19, heart attacks, respiratory arrest, strokes, etc.) and sent him to an ER that was prepared to treat him. He died on the way, and I bet that was in an ambulance with EMTs.

Supermarkets and auto supply stores don't treat medical emergencies, either. It's not Republicans or Democrats that are responsible for his death. Even with full-on single payer, urgent care would send him to an ER.
