According to historian Glenn W. Lafantasie, who believes James Buchanan the worst president, "Johnson is a particular favorite for the bottom of the pile because of his impeachment ... his complete mishandling of Reconstruction policy ... his bristling personality, and his enormous sense of self-importance." Tolson suggests that "Johnson is now scorned for having resisted Radical Republican policies aimed at securing the rights and well-being of the newly emancipated African-Americans."
Gordon-Reed notes that Johnson, along with his contemporaries Pierce and Buchanan, is generally listed among the five worst presidents, but states "there have never been more difficult times in the life of this nation. The problems these men had to confront were enormous. It would have taken a succession of Lincolns to do them justice."
Trefousse considers Johnson's legacy to be "the maintenance of white supremacy. His boost to Southern conservatives by undermining Reconstruction was his legacy to the nation, one that would trouble the country for generations to come."
Gordon-Reed states of Johnson:
We know the results of Johnson's failures—that his preternatural stubbornness, his mean and crude racism, his primitive and instrumental understanding of the Constitution stunted his capacity for enlightened and forward-thinking leadership when those qualities were so desperately needed. At the same time, Johnson's story has a miraculous quality to it: the poor boy who systematically rose to the heights, fell from grace, and then fought his way back to a position of honor in the country. For good or ill, "only in America", as they say, could Johnson's story unfold in the way that it did.
