Joe's problem is irrelevancy.
He doesn't have a job so his comments all sound like an outsider being critical but doing nothing.
Cuomo has an important job and is running around getting it done. He, like most governors, realizes that he needs the federal govt and he needs support from the President so he has holstered his tongue, mostly, and is working with the feds like you would expect your governor to do.
Same with Newsom. If you are actually trying to run your state in a crisis it makes sense to make nice with the President if you are trying to help your citizens.
Joe, otoh, has no active role in the recovery and so simply remains political and partisan sounding. Big mistake but what do I know?
Joe should channel Reagan and say that people should pull together, support their government and be considerate of others. He should say something positive about America and its ability to confront disasters. He should turn up at a food bank and help box food for people. It wouldn't kill him.
