Politics
Owing to its Yankee heritage, which contrasts with the German-American or Scandinavian-American character of most of Wisconsin, Walworth County was initially a stronghold of the Free Soil Party. It voted for Martin van Buren and John P. Hale in Wisconsin's first two presidential elections, and its opposition to the spread of slavery meant it became Republican in subsequent elections, even resisting the appeal of Wisconsin native Robert La Follette when he carried the state in 1924.
Walworth County remains strongly Republican. The only Democrat to carry the county was Woodrow Wilson in 1912, who won 36 percent of the vote. Even with the GOP mortally divided between President William Howard Taft and Theodore Roosevelt, Wilson only won the county by 29 votes. The best Democratic showings since then have been by Lyndon Johnson in 1964 and Barack Obama in 2008, both of whom received around 48 percent. Franklin D. Roosevelt and Bill Clinton are the only other Democrats since Wilson to cross the 40 percent mark, though Joe Biden came very close in 2020.
