I fully agree that Trump could have handled the virus better. Unfortunately, ALL media attention was focused on his impeachment at the time and he was derided as a racist and tyrant for banning China travel.
He should had the courage to ban all international travel immediately when the virus got to the EU and begun to initiate national readiness. Some nations did this and suffered far less as a result. Sadly, he - like so many national leaders - took the virus seriously far too late.
The final verdict on the efficacy of masks against this virus is still TBD once we have more information and the passage of time removes the political agenda's that cloud this conversation. Your "own the libs" certainly doesn't help either.
Though IMHO, given the role vitamin D deficiency seems to have on mortality rates, I think the harshest criticism (charges?) should be reserved for any mayor who ordered tanning beds to close in his or her city.
