The Democratic ones were ok to good - only the other Republican presidents were bad, Trump being not so much the worst one as the last straw, or ton of bricks in his case.Well, the good news is that it's hopeless and the other Presidents were bad as well.
And it only became hopeless with Trump, who managed to get the bus all the way over the cliff; before Trump walked into the White House, found the nearest commode, and began tweeting, the US had
1) an agency staffed by experts put together for the exact purpose of responding to the early signs of a pandemic by coordinating the national response. They had set up, in advance, the connections and contracts and formal waivers and so forth necessary to ramp up production of ventilators and acquisition of emergency hospital beds and development of diagnostic tests and distribution of masks and gloves and deployment of National Guard and other military resources and requisition of quarantine facilities and so forth - ready to launch on iirc three days notice, in response to
2) a division or sub-agency ("PREDICT") put together and funded for the purpose of spotting outbreaks of epidemics that could become pandemics, using circumstantial clues that did not depend on accurate information from foreign governments or sophisticated medical care systems, so the US military, diplomatic, and pandemic response agencies would have as much warning as possible (they would have spotted this one by the end of December at the latest, which means we would be more than two months into ventilator production and have plenty of cheap masks by now - as well as having flattened that famous curve considerably.
3) a small group led by an experienced medical and diplomatic professional stationed in China near Wuhan and with personal as well as political connections among Wuhan's hospital staff and public health administrators, with the express purpose of getting early info about epidemics informally, before the Chinese government went public.
4) the collected information and experience of a team of epidemiologists and related pros who had wargamed various scenarios including - just a couple of years before - a breakout of a newly mutated zoonotic coronavirus from Asia that could spread as a respiratory infection (they were spitballing a worst case - they chose a respiratory coronavirus because it combined rapid spread with lack of a vaccine - possibly no vaccine, as no one has yet developed an effective coronavirus vaccine).
Had Trump not thrown all that preparation away, dismissed all that expertise from government service and ignored all that information, we might be facing the quarantine of a couple of cruise ships and some foreign travel restrictions trapping tourists abroad, with the dead numbered in the tens and a half dozen hospitals dedicated to treating the sick.
And that is a refrain that needs to be repeated, pounded home with a sledgehammer: this, the US government's response to this natural disaster of continental scope, is what the Republican Party has become.
