The WHO recently said the lockdowns Biden says he's bringing back were causing more harm than good. That should be easy to find.

The early CDC tests, during the period we might have been able to maintain contact tracing, were faulty. A different president wouldn't have changed that.

Republicans didn't embrace masks, but it's unlikely a Democrat president would've done a better job convincing them.

In my opinion Trump's worst fault here is that he lacks the temperament for one of the most important things we needed: fireside chats. Trump is a pretty good hype man, cheering on good times, but abysmal at the somber tough message delivery we needed.
