I'd argue (and did at the time) that most countries were too late in locking down. Earlier, stricter lockdowns would likely have been shorter in duration, and cost fewer lives. But this pattern is reflected around the world, and says nothing particular about Trump. Politicians tend to be reactive rather than proactive with these things - if a precautionary action is going to cause economic damage, they won't act until it's absolutely necessary (and therefore too late).
This is part of the reason why I never blamed Trump for killing his geriatric consistency, as often he was accused of by the left. Is anyone truly under the notion that the complexity of an unknown virus with high transmissibility was handled with grace by any country? I look at the COVID death rates per capita by country, and I don't see any correlation between lockdown strategy and lower death rate. The response to COVID was in real time; there was no time for preparation.
For Trump, his reelection chances plummeted when the media held him personally responsible for killing hundreds of thousands of Americans. He seemed to be the only politician in the world held to that standard.
