The fact that states had inadequate PPE, beds, respirators, etc. is 100% on them. Inexcusable. The federal government did a Herculean job of filling that breach IMO.Agreed, so I'll clarify. I think the federal response (if you wish to consider their actions a "response") has been simply poor, full stop.
You statement, " Indeed, one can make a reasonable case the federal government's supportive response would have been adequate if states had been properly prepared" is something I simply disagree with. I don't believe there's a reasonable case that can be made to defend this administration's actions in response to the pandemic.
And I consider myself someone inclined to give any administration the benefit of the doubt, and won't persecute them over the timeliness of their initial response, because so much was unclear.
But the actions once it became more clear that this was a global pandemic IMO were more than lacking, they were made not with the public health of Americans in mind, but with the focus on how this might affect the perceptions of Americans regarding the economy.
Which in turn led to manipulation and interference with otherwise well-intentioned public health experts in this administration who had both efforts and statements edited to fit a reelection narrative.
The fact that states looked to the federal government for guidance on what to do during a pandemic is also inexcusable. This is exactly what states should have been prepared for.
I am convinced that the Trump Administration messaging was very imperfect, but in the big picture of things this was a comparatively minor failure.
