Experts say Trump is “easily the worst president in U.S. history.”

Michael Bailey, a political scientist at Georgetown, recently told The New York Times that President Donald Trump is “easily the worst president in U.S. history,” after the convicted felon posted a chart disparaging his predecessors and placing himself above George Washington, Abraham Lincoln, and Franklin D. Roosevelt.

“Trump’s stupid chart of ‘greatest’ presidents is a chart from Life Magazine in 1948, with his name added at the top and the Democrats he doesn’t like at the bottom,” wrote conspiracy theory expert Mike Rothschild. “Exactly the kind of thing a healthy, high-functioning person shares.”

The “Presidental Greatness Project” by University of Houston political science professor Brandon Rottinghaus and Coastal Carolina University political science professor Justin Vaughn, asked academics to rank each of the 45 people who have served as president all the way from George Washington to Joe Biden.

The survey is based on 154 responses from scholars across multiple disciplines, all of whom, in some way or another, engage in presidential politics through their work.

Trump was identified in the poll of experts on the American presidency as the worst president that the United States has ever seen.

Lincoln was rated the greatest president with an average score of 93.9/100, followed by FDR (90.8), Washington (90.3), Theodore Roosevelt (78.6), Thomas Jefferson (77.5), Harry Truman (75.3), Obama (73.8), Dwight Eisenhower (73.7), Lyndon Johnson (72.9) and John F. Kennedy (68.4).

Trump was the lowest-ranked president (10.9) behind James Buchanan (16.7), Andrew Johnson (21.6), Franklin Pierce (24.6) and William Henry Harrison (26.1), who rounded out the bottom five.

Without provocation or congressional authority, Trump launched the war in Iran, measles and explosive diarrhea are spreading across the country, the nation’s debt soared past $40 trillion as the federal budget deficit climbs to record highs, and ICE is increasingly arresting immigrants with no criminal record.

None of this is helping working-class Americans afford basic necessities or preventing any of the existential menaces that threaten human extinction.

Despite all that, Trump declared himself “the greatest” president in U.S. history in a ranking he posted to his social media site on Thursdayhile leaving nearly a dozen of his predecessors off the list entirely.

The graphic divides the presidents into six tiers: “The Greatest,” “Great,” “Near Great,” “Average,” “Below Average,” and “Failures,” with Trump alone occupying the top category.

The chart appears to be an altered version of a presidential ranking published by LIFE magazine in 1948, based on a survey of 55 experts in American history.

The version Trump posted largely preserves the original rankings and omissions, but adds three recent Democratic presidents to the “Failures” tier, one to the “Average” tier, and Trump’s name to the top.
