How, exactly?
For starters, he will pursue tests which are actually accurate and fast so we can quarantine people before each cluster spins out of control (like is happening now)
He will utilize the defense act to build and source what we need here in the U.S., versus assume the virus will magically go away. (After 7 months we STILL do NOT have the supplies we need.)
He will then establish a platform for leading scientists to share the TRUTH (there's a new concept) with the American people and allow them to speak freely which will dramatically improve the confidence in our experts and what they want us to do to get out of this mess.
He will listen to the FDA and other experts, versus push an agenda not founded in facts, like bleach, like Hydroxychloroquine, like a big breakthrough annuncement and pre-approval of plasma therapy only to have experts say it's not ready. (using up any confidence people had left in our current leaders.)
He will actually model the behavior needed (ie mask wearing, social distancing, shutting down major covid spreader events economic shutdowns as needed to make the case loads manageable, versus assuming it can't be done. (other countries have already proved that it can) A leader always gets better results than someone who can't maintain credibility.
He will let all major vaccine and therapy ideas to compete fairly versus picking winners and trying to financially benefit from the ones selected.
Etc..
Bottom line: By using science, past lessons learned on process control, obtaining better/faster measurements so we aren't flying blind and then putting in place the supplies, guidelines and conditions required to slow the increase in cases and then ACTUALLY following them will make a BIG difference. It is also the best chance at restarting our economy. As long as we have 30,000 cases/day we are dead in the water !
The alternative is chaos worse than we have now. (As more people are layed off and our government goes further into debt) That looks like a depression to me and full-fledged riots when more people die and kids go hungry)
If you disagree, tell me how Trump is going to make it go away in the next 2-3 years and how it WILL NOT exceed the deaths seen in world war II ? (something which I see as a given with him still in office) Also tell me how we are going to convince enough people to take ANY vaccine when he has NO CREDIBILITY - ZERO ! ! My family won't take anything coming out of HIS experts - it's snake oil ! Tell me HOW he is going to get the economy going again ! Opening up businesses will NOT make people come. Opening up schools will NOT provide good education when the teachers get sick, retire or change jobs.
