Politics

In its early days Marshall County was a swing county, voting for winning Whig candidate William Henry Harrison in 1840 but otherwise supporting the Democratic Party until 1852. Its reputation as a swing county was to be sustained with the growth of the Republican Party: it voted for the winning candidate in every election from 1852 to 1912 except 1884 and 1888.Template:Citation needed

Since World War I, Marshall has generally been a strongly Republican county. Only two Democrats – Franklin D. Roosevelt in 1932 and 1936 plus Lyndon Johnson in 1964 – have gained an absolute majority in Marshall County over the past twenty-six elections, although Bill Clinton won pluralities in both his elections.Template:Citation needed
