Politics
For most of its history, Columbia County voters have backed the Republican Party candidate in national elections. Prior to 1992, the only times Republicans failed to win the county in the preceding 100 years of presidential elections were in the midst of a divided party vote in 1912, in 1924 when Wisconsinite Robert La Follette was on the ballot, and in the national Democratic Party landslides of 1932, 1936, & 1964. From 1992 onward, the county has been a Democratic-leaning swing county, voting for the statewide winner in all presidential elections since then except in 2004 and 2020, and voting for the national winner in all except 2000 and 2020. Republican Donald Trump won narrow pluralities in the county in 2016 and 2020, although a majority of county residents supported Democrat Tammy Baldwin's re-election to the United States Senate in 2018.
