It's worth remembering that the only really consistent Trump policy was to cancel every program, treaty, policy, or law from the Obama administration, and replace it with nothing. He cancelled the CDC's collaboration with the Chinese to monitor for emerging viruses, with the result that we were unaware of the Covid outbreak for months. He ignored the national pandemic response plan that was developed after the H1N1 outbreak, and failed to develop any national plan of his own. He went so far as to tell states they had to order their own PPE, setting up a scenario where states had to bid against each other and drive up the price, then he seized shipments destined for blue states and sent them to states whose governors sucked up to him. It's true he did allow the government to fund fast-tracked vaccine development (though that was a "no-brainer") but then he failed to develop any sort of a plan to distribute the vaccines, and blocked the incoming Biden administration from getting the information they needed to develop their own plan. Apart from Covid, he cancelled the program for dealing with black lung disease, and replaced it with nothing. He withdrew the US from the WHO, leaving us with no mechanism for collaborating with other countries to deal with a world-wide pandemic. He withdrew from the Iran nuclear deal and replaced it with nothing, with the result that Iran stopped abiding by the deal and is now closer to a nuclear weapon than the have ever been. I could go on and on and on. Hatred of Obama is not a substitute for a national policy on anything. Hundreds of thousands of people died as a result, and people will be worse off for a long time because of Trump's obsession with erasing Obama from history.
