RANKED: The 15 most polarizing presidents, according to political scientists

Presidents Donald Trump and Barack Obama are among the most polarizing presidents in US history, according to nearly 200 political science scholars.

A survey published last month asked 170 current and former members of the American Political Science Association to rank up to five presidents they believed to be the most polarizing.

The presidents were then ordered based on the number of times they were identified by respondents as well as their average polarization rank.

It's worth noting that a majority of the respondents - roughly 57% - identified as Democrats and just 13% were Republicans, so it's not surprising that Trump was ranked so unfavorably. But even Republicans viewed Trump negatively, according to the survey.

"On average, Republicans view President Trump one full spot less polarizing than Democrats," the survey said.

Obama, on the other hand, was ranked roughly the same by Democrats and Republicans alike.
