American historians have recently ranked Donald Trump our worst president to date. There is, as you might imagine, some disagreement that breaks down along partisan lines in these surveys of the experts, but even the Republican historians still rank Trump among the worst five we've ever had.
Some might argue that it's unfair to include Trump in these rankings based on only a single year in office, and particularly unfair to rank him the absolute worst president in U.S. history considering that he hasn't yet led us into any true national catastrophes like say a civil war or an event like the Great Depression, for example. But clearly historians look at this administration and see great potential.
