Worst: Andrew Jackson, Jimmy Carter, and a 4 way tie for the real worst Zachary Taylor, Millard Fillmore, Franklin Pierce, and James Buchanan for allowing the Civil War to happen.
Best: George Washington (started the step down after 2 tradition), Jefferson (purchased the best real estate deal ever plus liked ethnic women), Lincoln (yup), and as a write in based on his best in modern times label George HW Bush for getting into a modern war and back out without fucking america.
