To celebrate President’s Day, data crunchers over at Dadaviz created an interesting chart that shows the approval ratings for every president since 1945. Using approval rating data from Gallup.com, this visualization was made to show how the past 12 presidents have stacked up against each other.

The spread varies term to term, with some massive differences within presidencies, as seen in George W. Bush’s rating, which peaked at 89% in the months following the 9/11 attacks, before slowly dropping to 25% over the course of his time as president. Others, like John F. Kennedy, had relatively small variation in approval rating — though he achieved the highest average rating by far. While Barack Obama’s spread is a lot less than the younger Bush’s, his average rating is just a shade below, at 48%.
