The Gallup Poll has recently called Donald Trump's job approval the most stable of all the presidents. That is not something Trump should be proud of though, since the stability has been due to very poor approval ratings since he took office. He is the only president who has never had the approval of a majority of Americans (with his highest approval being 45%). And his lowest approval at 35% has been lower than all but one president (Truman).
Trump also trails all other presidents in average job approval. His average is 39% -- the only president to have an average below 48%.
Donald Trump is the most disliked and least respected president since World War II.
