You can read my posts in the 2020 presidential election thread, as well as the COVID-19 thread, explaining how the pandemic was utterly mishandled by the Trump administration. Among numerous other things, Trump told people to go about their business as usual, described it as only the flu, was anti-mask, and did pretty much everything he could to court antivax voters without outright coming out against the vaccine (going as far as to hide the fact he was vaccinated). They had virtually no plan to roll out the vaccine, and he also suggested ingesting bleach might be an effective treatment against COVID-19.
