How bad is it going to have to get for even Trumpies to admit Trump's priority all along was for his re-election and not for the welfare of the country concerning combating the virus.

And then, how bad would it have to get for Trump to actually wear a mask in public (consistently) and personally ask his supporters to do the same?

Anything he has done good while in office is overwhelmed by his total failure in the country's time of need and unselfish leadership.
