Like most other counties anchored by an urban population center and a large public university, Dane County is solidly Democratic, with a long history in the progressive movement. It has backed the Democratic presidential nominee in every election since 1932 with the exception of the two nationwide landslide victories of Dwight D. Eisenhower in 1952 and 1956, and even then, Eisenhower's margin of victory was under 3% both times. Since then, Republicans have only crossed the 35% mark six times. Within Wisconsin, only the predominantly Native American county of Menominee is more reliably Democratic.
At state level, the county is no less Democratic. The last Republicans the county supported at state level were Governor Tommy Thompson and Treasurer Jack Voight in 1994.[12] [13] The last Republican Senator to carry the county was Alexander Wiley in 1956 by less than one percent, 10 years earlier the county was the only one in the state to not vote for notorious Senator Joseph McCarthy.[14] [15] In the three-party era of 1930s-1940s, the county backed Progressive Party candidates, such as the La Follette brothers, Orland Steen Loomis and Herman Ekern.[16] [17]
Dane County is one of the only counties in the United States to have elected a member of the Green Party (Leland Pan) into county-level office.
See main article: Administrative divisions of Wisconsin.
Cities are incorporated, generally have a mayor (or a administrator/manager), an elected council, and generally provide more services than smaller administrative divisions.
Villages are incorporated, are governed by a Village President and Board of Trustees, and provide residential services.
Towns may have the same name as a city or village associated with it, but it is a separate municipality. Towns are not incorporated, are governed by a town board, and only provide limited services to residents.
Unincorporated communities are smaller communities that are governed by the town they are located in and often exist as nomenclature in vital records.
Neighborhoods exist mostly for nomenclature purposes; some may have administrative associations with powers that are defined in the property deed covenants of the neighborhood. This is a partial list that primarily consists of former unincorporated communities that are now within the boundaries of an incorporated city or village.
