Theodore Roosevelt was a bad president

Scientifically proven - Trump worst US president of all time

Compared to 2014, when the last ranking of the American presidents was published, the undisputed worst among the rated heads of state, James Buchanan, lost his last place to Donald Trump. Buchanan is considered to be one of the main people responsible for the bloody civil war that ravaged the United States between 1861 and 1865 and divided the nation - noticeably to this day.

In first and second place are two historical figures unchanged: Abraham Lincoln, the great unifier of the nation, who was murdered on April 15, 1865 by John Wilkes Booth, a secessionist. Second place is held by George Washington, who was the first President of the United States in office from 1789 to 1797. To date, Washington is the only president to have received all electoral votes. He laid the foundation for modern America, his refusal to rule a third term led to the tradition that US presidents can only be elected for a maximum of two terms.

Obama is the biggest climber

The scoring system after the scientists created the presidents' competency ranking goes from 0 (failure) through 50 (average) to a maximum of 100 (great). Trump received 12 out of a possible 100 points. Lincoln got 95 points, Washington 93 points. Franklin Delano Roosevelt (1933 to 1945) holds the best position of a post-war president, who is unchanged in third place with 89 points. Fourth was his distant cousin Theodore Roosevelt, the 26th President of the United States. The biggest climber is President No. 43, Barack Obama (71 points), who made it to 8th place. In 2014, Bill Clinton was still there - he is in 13th place in 2018.

It is also interesting that the avowed Republican scientists only put Trump in 40th place (out of 44). The independents (to be assessed as more conservative) placed Trump in 43rd place, among the Democrats voters among the researchers Trump came in last with only 8 points, Buchanan still received 16 points. John F. Kennedy made it to 16th place, George W. Bush 30th and his father George Herbert Walker Bush 17th.

The bottom line from Professors Brandon Rottinghaus from Houston and Justin S. Vaughn from Idaho, who oversaw the study: Trump's first placement is a shame, but there have been dozens of presidents who got off to a bad start and later changed their line to gain more support .

Either way, there is still room for improvement for No. 44.
