The governors and mayors of these states have the power right now to rescind the stay-at-home order any time they want. The Feds are just providing guidance to help them with their public health responsibilities. If the cases in their cities don’t spike they will be like the first people back in the water after a shark sighting. Everybody else will feel safe to join them.
If they are early and the virus overwhelms their health care system, people will die that didn’t have to. I’m not sure most politicians would take that bet.
and, we should probably all try to get in better health..
