Government

McLean County has a twenty-member board representing ten districts within the county. Each district elects two members. Districts 1-3 encompass all of the county outside of Bloomington and Normal. Districts 4-6 are within the town limits of Normal, and districts 7-10 are within Bloomington city limits.

Politics

[edit]

Like most of central Illinois, McLean County is historically Republican-leaning. The only Democrats to gain an absolute majority of the county's vote before the 21st century have been Franklin D. Roosevelt in 1932 and 1936, and Lyndon Johnson by a mere 1.2% in 1964. Woodrow Wilson in 1912 and Illinois resident Barack Obama in 2008 both carried the county by narrow pluralities.

In recent years, however, McLean has trended sufficiently Democratic that Hillary Clinton in 2016 lost the county by just 1.3 percent, while Joe Biden won the county in 2020 with a narrow majority.

Further solidifying the county's leftward shift in the 2020s, Governor J. B. Pritzker won the county by 1.3% in 2022, making it the first time since 1948 it supported a Democrat for governor. In 2024, Kamala Harris became the first Democratic presidential nominee to win McLean County yet lose the presidential election.

McLean County is one of only thirteen counties to have voted for Obama in 2008, Romney in 2012, Trump in 2016, and Biden in 2020.[a]
