Organizational scientists have conducted many experiments which all confirm that when things are good for any group the best approach to success is to be as visible as possible, even if you have nothing to do with the positive situation... AND... when things are going poorly, to hide! Jimmy Carter was an unwitting victim of the rise of OPEC, which devastated the US economy and resulted in his defeat. He had no blame in that unhappy moment but nonetheless got tagged. Regardless of whether Trump deserves liability for the COVID crisis, if it is not mostly resolved by November and the economy is not on a serious upswing in battleground states he does not have a snowball's chance in hell of being re-elected.
