Fauci was predicting a minor inconvenience in the early days and very few deaths. He was wrong. Trump listened to Fauci and also needed to convince the American people that there was no real danger to avoid panic. If you think Biden (or ANY politician) would have made any difference in the response you should keep taking what you are taking because you have no business trying to deal with reality.
Fauci can look at it from a purely clinical assessment and state that we CAN limit the outcome of any virus pandemic if we only quarantine everyone 100% of the time needed for exposure and recovery (if someone ALWAYS lives or dies within 30 days of exposure) and is "safe" 10 days after recovery. Close the country, seal everyone in their homes for 45 days and the virus is gone. That works with a small population but a nation of 330M of free people and not so much.
Panicked morons buy all of the toilet paper, clear out the ground beef, soup, etc. They don't work, they don't pay taxes, they don't send kids to school. We can see the influence and fears of morons every day. So there has to be a little calming influence, unfortunately for America, the guy charged with being the calming influence is Trump. Half of the elected officials in Washington, 90% of the press, and 100% of the Hollywood idiots detest Trump and so anything said to calm fears is immediately cast as a lie. 90% of the crap Obama spewed regarding the recession was 110% bullshyte, yet the press went along with it - the same can be said of half the works of FDR, Truman, Eisenhower, Kennedy, LBJ, Ford, Clinton, GW Bush..... Never mind that Presidents from George Washington on down have tried to calm the morons by projecting what they would like to see, whether that was realistic or not.
Just like FDR when briefed about the upcoming D-Day and Truman when briefed on the plans to invade Japan you look at the numbers and are appalled. But the people doing that planning have done the math. If you understand that, then the panic is stupid. If you want to go back and look at the projections, no one was saying that we would be able to keep deaths under 50K, it was 50K by Memorial Day, it was 100K by 4th of July...... It's 200K by Labor Day..... without a vaccine, everyone eventually gets this and they will live or die. There's not a thing that can be done to change that, the only question is timing. The question no one is addressing is if the disease does NOT produce long-term antibodies - how does a vaccine save anyone? In 1918, they attempted to slow the progression but eventually around 60% of the global population was infected with the virus (so 1.2B of nearly 2B people) and a death toll of around 50-100M. What stopped it was not face masks, social distancing, a vaccine, or a specific treatment - we reached global herd immunity. That is what we are looking at and all we are doing is delaying the inevitable. Real epidemiologists have run the numbers, we cannot close the planet, face masks, social distancing, etc. flattens the curve -which means prolongs the inevitable. It doesn't eliminate anything, it just lengthens the time period. Thinking about 500K Americans dying in a single year is appalling, but if you knew we could drag it out to 2-3 years does that make the number any less appalling? If it is inevitable, other than protection of our medical industry, why wait?
