McLean County leans modestly Democratic at the presidential level, a shift driven partly by the student and professional population clustered around Bloomington-Normal, even as surrounding rural areas trend in the opposite direction.

The Democratic margin in McLean County has rarely exceeded twelve points in modern history; the Republican margin has rarely exceeded forty points. 2024 delivered the county to the Democratic candidate by five points.
