He’s the greatest at being the worst, according to a new poll.

President Donald Trump came in last in a poll of political scientists that ranked all 44 of the people who have served as chief executive.

Abraham Lincoln, George Washington, Franklin Delano Roosevelt and Teddy Roosevelt in order took the top four spots in the Boise State University “Presidential Greatness Survey.”

The poll quizzed “current and recent members of the Presidents & Executive Politics Section of the American Political Science Association,” described as “the foremost organization of social science experts in presidential politics.”

Out of the 320 political scientists contacted between Dec. 22 and Jan. 16, 170 complete responses were received.

They were asked to rate each president on a scale of zero to 100, and then the scores were averaged together for each president.

Thus, Lincoln got a rating of 95.03, while Washington got a rating of 92.59.

Presidents Thomas Jefferson, Harry Truman, Dwight Eisenhower, Barack Obama, Ronald Reagan, and Lyndon Johnson rounded out the top 10.

Trump’s rating? A lowly 12.34 — or last of 44 different presidents. (Trump is the 45th president, but one of his predecessors, Grover Cleveland, was elected two separate times, making him the 22nd and 24th president. He came in at No. 24 on the survey.)

Trump was rated even worse than President Richard Nixon, who came in at No. 33.

Nixon quit under pressure from the Watergate scandal.

Trump was also rated below William Henry Harrison, who died after only a month in office — from March 4, 1841 to April 4, 1841.

Even Warren Harding, whose presidency was afflicted by the Teapot Dome corruption scandal and his dalliances with mistresses, rated higher than Trump at No. 39.

Trump “won” another category — most polarizing president. He was well ahead of No. 2 — Andrew Jackson.
