One never wants to have a reason to revise a worst president list. I basically stand by this 2011 list I made, although I think the similarities in corruption between Trump and Harding are going to drop the latter down the list and at this point I would flip Johnson and Buchanan. But I really wonder if Trump will indeed be the worst president in American history, even beating out James Buchanan and Andrew Johnson. With all due respect to the horrors caused by both of those men, I suspect it is even odds that the answer will be yes. And that is deeply, horrifyingly disturbing.
