The US has had several really bad presidents so this is not a modern phenomena. In 1948 Warren G. Harding, Ulysses S. Grant, Franklin Pierce, James Buchanan and Zachary Taylor were named the five worst presidents in American history. In a 1982 poll, the list was the same, save for Andrew Johnson taking Taylor's spot in the bottom five.
Perhaps Trump will sink to the bottom 5, but a single term isn't like a two term President's chance to muck up the economy.
George W. Bush and Richard Nixon were among the bottom 10 in 2014, but climbed out from the dregs of American leadership in 2019. Perhaps it is the ability to compare in hindsight that gives us a balanced opinion.
