Clallam County was a bellwether, holding the longest record, until 2024, for predicting official presidential election winners in the entire country. In every election since 1920, except for 1968, 1976, and 2024, it has voted for the presidential election winner.

It voted the winning candidate in every presidential election from 1980 to 2020, the longest streak of any county in the country before ending its streak in 2024. Clallam County also voted for Bob Ferguson in the 2024 Washington gubernatorial election for the first time since the 2000 Washington gubernatorial election, despite Ferguson underperforming Kamala Harris, indicating a potential leftward shift in the county.

Democratic candidates are generally most successful in the county seat and largest city, Port Angeles, which casts a significant number of votes. The city of Sequim and its general vicinity (excepting newer developments such as Bell Hill which tend to be Republican) is generally considered a battleground area. The Forks area is generally Republican, with the exception of American Indian areas. The Makah tribe areas around Neah Bay are some of the most Democratic areas in the state. Otherwise, with the exception of a few locations (such as Blyn and Jamestown near Sequim), unincorporated Clallam County has a strong Republican lean.
