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.

In state elections, 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. 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 Republican Senator Joseph McCarthy. In the three-party era of 1930s-1940s, the county backed Wisconsin Progressive Party - National Progressives candidates, such as the La Follette brothers, Orland Steen Loomis and Herman Ekern.
