A recent survey of 142 presidential historians conducted by C-SPAN continued the tradition of ranking former executives based on a wide range of criteria. Each respondent issued a score from 1 (meaning “not effective”) to 10 (meaning “very effective”) in 10 categories that encompass presidential leadership: crisis leadership, public persuasion, economic management, moral authority, international relations, administrative skills, pursuing equal justice for all, relations with congress, vision or setting an agenda, and their performance within the context of the times. The average of each president’s responses was then added to rank them overall, with each category given equal weighting. New questionnaires are issued at the beginning of every new administration so that only former presidents are included in the rankings, meaning you won’t see current President Joe Biden on this list. The latest survey also invited dozens more respondents to participate so as to create “new diversity in race, gender, age and philosophy” in the results, C-SPAN said. (Here is a full list of the historians surveyed.) Each time the survey is conducted, presidents rise and fall among the ranks, and this year is no different. With everything considered from impeachment to landing on the moon, here is every former president of the United States ranked from best to worst, according to historians.
