I, for one, am in no way happy with the handling of the pandemic on a national level. However, the truth is that our state constitutions handle how health emergencies will be handled within the individual states. It's the law and that's just how it is.
The feds could do a hell of a lot more than they have, however, in management of resources like PPE, ventilators, etc., providing straight and transparent information about the pandemic, assisting the states with funding, etc. And yes, the federal government could have made a lot more scientifically-based, consistent, strong recommendations as to handling of this crisis.
