He doesn't. He gets more blame than others because he is POTUS and they get attacked for ridiculous things all the time anyways. Most importantly he gets more blame because of his own specific actions/words.
Go into other threads and people have criticized specific democratic governors responses and there has been sharing of someone like I think it was DeWine handling it well the other way.
