Smearing the death rate out across the entire US is misleading when the variation is huge. New York State is, by head, the worst-hit region anywhere, and two other states also appear currently to be running ahead of European countries.
Trump's connection to those particular chilling stats is incidental at best, to be sure. Where the criticism comes from, though, is in the contradictory advice, the hubris of February-March, the undermining of his own health experts, the claims and then rapid retractions of unconstitutional powers, attacks on governors, the strange decision to briefly encourage anti-lockdown protests, and so on.
Also there's the question of Trump's travel ban. In itself I don't think it was an unreasonable decision, except that it was probably already too late for such measures to have a meaningful impact. What's frustrating is Trump's continued insistence to credit that decision for saving lives when, at most, it merely delayed the outbreak, buying time that was then not really put to good use. That's the criticism. Why was Trump boasting about his actions early on when he certainly should have realised that there was worse to come? What was this nonsense about there are only 15 cases and it's going to go "down to zero very soon", or "the Coronavirus is very m uch under control", ir his classic 9th March proclamation:
// So last year 37,000 Americans died from the common Flu. It averages between 27,000 and 70,000 per year. Nothing is shut down, life & the economy go on. At this moment there are 546 confirmed cases of CoronaVirus, with 22 deaths. Think about that! //
Well, Covid-19 has now exceeded 70,000 in the US in barely a month.
I could go on. Trump has been clearly and sad out of his depth, which is a problem.
