As the article states, ranking presidents purely by GDP is unfair for many reasons. The president, after all, has limited control over both the economy as a whole and over the government’s policy toward the economy. In addition, every president does much more than simply make decisions on economic policy. Nonetheless, looking at the rankings is rather interesting. These rankings cover all presidents who have entered office after WWII. As you can see, Presidents Kennedy (5.4%) and Johnson (5%) are numbers 1 and 2 on the list, respectively, while Presidents Obama (1.2%) and George W. Bush (1.6%) have posted the lowest GDP growth numbers.
