America is in ruins, so not an excellent job, but you could argue that no one could do an excellent job in such terrible circumstances. We are towards the bottom of the stack in responses, so not even an excellent job compared to other leaders. There is a reason that trump is one of the few leaders not to get a Covid-19 bump out of this crisis, and that is because he is doing in no way an excellent job.
You do not seem to know what rate of infection means. Having more people infected would drop the rate of infection, because there would be fewer people to infect.
trump did not stop travel from China. he did not check for infection at the border. So he did allow a huge number of infected people in. And then he lacked the ability to track the spread once it had gotten into the USA. It would be hard to do worse. Most of the successes in containment can be put at the feet of governors. You know the same governors that trump has demanded violence against.
