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 RepublicanTheodore Roosevelt won the county as theProgressive candidate and in 1924 whenProgressive and native WisconsiniteRobert M. La Follette won the county. Then, between 1932 and 2012, Polk County was a very consistently competitive county that leaned slightly Republican. Only two candidates in that span won at least 60% of the county's vote,Dwight D. Eisenhower in his 1952 landslide andLyndon B. Johnson in his 1964 landslide. Polk County took a rightward turn in 2016, whenDonald 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. Trump won in 2020 with the exact same margin of victory of over 27% while increasing his vote share to nearly 63%. In 2024, Trump once again improved on his previous performance, taking nearly 65% of Polk County's vote and defeatingKamala Harris by more than a 30% margin.
