In addition to what everyone else has said to point out how absurd it is to put Trump in the top 5 worst presidents, there's also the fact that almost every significant Trump policy was continued or worsened by Biden. Even the ones that democrats pretended to care about when it suited their agenda like kids in cages, building the wall, and increasing fossil fuel extraction. So if you want to talk about all the ways Trump is an evil piece of shit (which he most certainly is) to put him in the top 5 worst, then you had better make sure Biden is even higher on that list.
