Indeed. Despite all of Trump's faults and failings, if he and his staff took this seriously from day one like many other countries did, he would have proven that maybe he really does deserve to be president after all.
And he failed. Spectacularly. This outbreak and his mishandling of it instead just proved how incompetent he truly is.
The only silver lining is that hopefully millions of Americans that voted for him in 2016 are seeing all of this, realizing their mistake, and will try and rectify this in November. But I have no faith in this country anymore, so I expect him to win by a bigger margin somehow.
