The 2018 Presidents and Executive Politics Presidential Greatness Survey, which ranks presidents from best to worst, was based on responses from 170 current and recent members of a section of the American Political Science Association, an organization of social science experts. "His average rating is 12.34, which is almost three points lower than James Buchanan (15.09), who previously occupied the lowest rank". Trump didn't even rank well among self-identified Republicans and conservatives, coming in 40th.
Abraham Lincoln topped the list with an average score of 95.03, followed by George Washington with 92.59.
They were asked to rate each president on a scale of zero to 100, and then the scores were averaged together for each president.
The survey was published and authored by University of Houstonâ€™s professor Brandon Rottinghaus and Bois State University professor Justin S. Vaughn.
Buchanan, the country's 15th president, has been criticized for failing to address slavery as the divided United States was on the brink of the Civil War.
At the time of his death, it was reported that he died of pneumonia after refusing to wear a coat during his two-hour inauguration speech.
He's the greatest at being the worst, according to a new poll.
"Trump's initial rating places him in an ignominious category, but dozens of presidents have had slow starts and have course corrected to improve their public esteem, " Rottinghaus and Vaughn wrote.More news: Mauricio Pochettino plays down FA Cup risk

Trump also "won" the most polarising President, ahead of Andrew Jackson who won the second position.
Since the last survey in 2014, several former presidents moved up on the list.
Sitting just above Trump on the survey list are James Buchanan (left) and William Harrison (right).
The biggest declines were for Bill Clinton, arguably the result of contemporary scorn for his treatment of women, and Andrew Jackson, for evolving attitudes on his treatment of Native Americans.
Trump's rating? A lowly 12.34 - or last of 44 different presidents. Reagan received high ranks from conservatives and Republicans but fell short with Democrats and liberals.
Even Republican raters put Trump among the worst presidents at No. 4.
The rating was the same percentage of registered voters who approved of the job he's done in office.
