Historical rankings of presidents of the United States - Wikipedia
Interesting to note in 2014 Obama was the 4th best and the worst. In 2017 Obama moved up to second best and at the same time, second worst behind Nixon. Another 2017 poll had Obama as the second best, behind Reagan and the second worst, behind Trump. 2018 continued with Obama behind Reagan for the best and second worst, just behind Trump.
