According to USA Today, 157 scholars surveyed by the Siena College Research Institute ranked Trump as the third worst president of all time. The two worst presidents were Andrew Johnson, who was impeached, and James Buchanan, as the civil war followed his presidency.
The Siena survey is conducted after every new president has one full year in office. Presidential scholars, political scientists, and historians are asked to rank the presidents in 20 different categories.
Generally, the current president comes somewhere in the middle of the rankings as the survey is conducted after only one year in office. But "This year, Donald Trump enters the survey at 42nd, and he is only ranked outside of the bottom five in two of the twenty categories that scholars use to assess the presidents, 'luck' and 'willingness to take risks,'" Don Levy, the director of the institute, said.
Also in the survey, Obama dropped two spots, becoming the 17th greatest president. George W. Bush rose six spots, becoming the 33rd greatest president. Clinton went from the 13th to 15th in ranking, and Reagan rose from 18th to 13th. The top five greatest presidents has remained unchanged. They are Washington, Roosevelt, Lincoln, Teddy Roosevelt, and Thomas Jefferson.
