McLean County s historically a Republican-leaning county. The only Democrats to gain an absolute majority of the county’s vote since the Civil War have been Franklin D. Roosevelt in 1932 and 1936 and Lyndon Johnson by a mere 420 votes out of over 38,000 total in 1964. Illinois-bred Barack Obama in 2008 and Woodrow Wilson in 1912 both carried the county by narrow pluralities. McLean has trended Democratic, sufficiently so that Hillary Clinton in 2016 lost the county by just 1.3 percent despite failing to win the Presidency.
