Politics From its founding in 1853 through 1928, Polk County was a strongly Republican county in presidential elections, never once backing the Democratic candidate. The only two times in that span it did not support the Republican candidate were in 1912 when former Republican Theodore Roosevelt won the county as the Progressive candidate and in 1924 when Progressive and native Wisconsinite Robert M. La Follette won the county. Then, between 1932 and 2012, Polk County was a very consistently competitive county that leaned slightly Republican. During the 1930s and 1940s at the state level Polk county was a stronghold for the Wisconsin Progressive Party–National Progressives. voting consistently for Philip La Follette during gubernatorial elections and Robert M. La Follette Jr. for senate.
Only two presidential candidates between 1932 and 2012, won at least 60% of the county's vote, Dwight D. Eisenhower in his 1952 landslide and Lyndon B. Johnson in his 1964 landslide. In 2016, Donald Trump won over 60% of the county's vote with a winning margin of over 27%, the best margin of victory in the county since 1928 with the exception of Johnson in 1964.
