Here is a comprehensive summary of the article:

Presidential job approval ratings in the United States were first introduced around 1937 by George Gallup to measure public support for the president during their term. While individual polls can be skewed by unscientific methods like self-selected online surveys, the aggregate approval rating is widely accepted by statisticians as a valid indicator of shifts in the national mood. The highest rating ever recorded in Gallup's tracking was 90% for George W. Bush shortly after the September 11, 2001 terrorist attacks, while the lowest was 22% for Harry S. Truman in a survey from February 1952. A significant recent development is that Gallup announced on February 11, 2026, that it would cease polling presidential approval ratings and those of other public figures. The article also includes historical comparisons, graphs, and links to polling data for specific presidencies, such as those of Trump, Biden, and Reagan.
