I think a lot of people misinterpret the "handling" of this and make it easy to blame the sitting president.
What, given the benefit of hindsight, would we have called for? Was Donald trump not the one who banned travel when everyone was saying he was overreacting?
What was he supposed to do? Come out and say "Oh guys! This is bad! We are screwed!" Had he acted like he was fearful, his opponents would have said he was weak and scared.
Without getting too long about it, a lot of people don't like the president's presentation and maybe that clouds things but looking back, he was acting more in making changes than anyone. Everyone else (Biden, Zeke, Crane, The NY governor, the NY chief of medical services, etc) were all on record saying it wasn't that serious. Dr. Fauci probably had the best perspective when he said at the time it wasn't a huge concern but it COULD change quickly.
I know some people will want to talk ad nadeem about masks or something and how it was so wrong but we need to remember that a LOT of people have been wrong about a LOT of this pandemic at times and made decisions on what they knew at the time.
I'm not saying it couldn't have been handled better (I don't think any of us are that omniscient with this) but I think its safe to say it could have been a lot worse and that it is reasonable that any other person, democrat or otherwise, would not have truly acted differently in an impactful way.
