Its tough when you have to rely on cooperation with the states but that doesn't exonerate him.
Firstly, why is his relationship so poor with all of the states and what role has he played in creating that relationship? He would stand a better chance if he didn't shitbag every democrat state and constantly blame them for everything. No-one is suggesting that he could have 'stopped a virus' (ridiculous exaggeration) but the constant whining and finger pointing between the feds and the states was a terrible look and did more harm than good.
That said, it is politics and the relationship will never be perfect and sadly, many states use moments like these to exercise their sovereignty.
I thought Trump did OK in the beginning but like a lot of things he got bored and was distracted by the next shiny ball. The fact that he went from almost daily briefings to pretending that it didn't exist (whilst the numbers were still growing) was so unbeliveably weird. He talks about the 'evil press' in the US but if ScoMo did something similar over here he would have been skinned alive! The merkin should have at least had the guts to stick it out and explain to people what was happening.
