The survey's goal is to rank presidential greatness, covering all presidents from George Washington to Donald Trump.
The 2018 Presidents and Executive Politics Presidential Greatness Survey, released Monday, was based on 170 usable responses from current and former members of the American Political Science Association's presidents and executive politics section.
Each expert who took the poll was asked to rate each president on a 0-100 scale, with 0 meaning failure and 100 meaning greatness.
Trump makes his ranking debut at the very bottom of the list.
According to a C-SPAN survey of the historians, Barack Obama ranked as the 12th best president, getting good grades for his vision and setting an agenda, managing the economy, public persuasion, "pursuing equal justice for all" and "moral authority". Lincoln came first with a score of 95, Obama came in eighth with a score of 71, just ahead of Reagan.
Things don't look so great for old Donny as he ranks dead last amongst the entire group, 45th out of 45. Roughly 57% of the respondents were Democrats, 13% were Republicans and 27% were independents (3% selected "Other").More news: Former Russian ambassador to USA calls allegations of Russian meddling 'hunting spree'

There are times when it seems no criticism of President Donald Trump would go too far among a large segment of blue check Twitter. Obama shot into the top 10, up from 18th when a previous survey was conducted in 2014.
Trump received three Fs and two Ds. He ranked 40th out of 44 among Republicans and conservatives.
The higher marks awarded Trump were in communicating with the public and foreign policy leadership.
Ronald Reagan jumped two spots from 11th to ninth, with an average of 69.24.
Trump was rated worse than President Richard Nixon, who quit under pressure from the Watergate scandal, ranking as 33rd.
Also, Republicans are super into some dude named William McKinley, who was assassinated while in office and led the country through the Spanish-American War. Trump still has time to turn things around, and many presidents' legacies improve over time, the researchers note.
