A president's approval rating affects their ability to push legislation through Congress, recruit candidates, and shape their party's midterm prospects.
It's a simple thumbs-up or thumbs-down on how the president is doing the job, reported as a percentage.
Approval numbers act as a running report card that can influence policy choices, staff changes, and the tone of public messaging from the White House.
Pollsters ask a version of: 'Do you approve or disapprove of the way the president is handling his job?' Responses are tallied as approve, disapprove, or no opinion.
Results are often averaged across multiple polls and charted weekly or monthly to smooth out short-term swings tied to news events.
Approval often rises during national unity moments (a 'rally effect') and falls during economic downturns, scandals, or unpopular policy fights.
