The focus is on dealing with the emergency. And we can't do that with someone sabotaging many of the efforts in that direction because he is worried about his re-election.
Want to deal better with Coronavirus? Appoint Mike Ryan, a doctor currently working with the WHO and on the United Nations crisis management team on the Coronavirus problem, to lead the response here. Give him immunity from Trump's whims, and prohibit Trump from tweeting or speaking about the pandemic for six months. The stock market will calm once someone competent is leading the shots, and the CDC will not suffer from Trump's whiplash-inducing reversals on the pandemic response.
Don't like Mike? Then appoint Nancy Messonnier, another doctor who is already with the CDC. Again, give her complete authority - and insulate her from Trump's desire to fire/muzzle/redirect her.
Or do nothing and expect a different result.
