Generally, Asotin County is considered a staunchly Republican area, although it has been known to vote for Democrats, especially on the state level. Currently the county is represented at the county level by two Democrats and one Republican.

In the 2000. Conversely, even though nearly 60 percent of voters selected the Democratic Governor Gary Locke in 2000, in 2004 the Democratic gubernatorial nominee Christine Gregoire received only 41 percent of the vote.

In 2004, 27% of presidential votes were cast from incorporated Clarkston, while 61% was from unincorporated suburbs of Clarkston (34% from Clarkston Heights, 12% from West Clarkston, 9% from South Clarkston, and 6% from Swallows Nest). An additional 6% was cast from the incorporated city of Asotin, with rural areas around Asotin accounting for 4% of the vote and areas around the unincorporated community of Anatone making up 2% of the vote.

By and large, the most competitive areas are Clarkston and its suburbs. Democratic presidential nominee John Kerry won two precincts in 2004, one each in Clarkston and West Clarkston. Bush received 54 percent of the vote in West Clarkston, 55 in Clarkston, and 57 percent in South Clarkston. However, he received larger victories of 64 percent in Clarkston Heights and 67 percent in Swallows Nest. Areas around both Asotin and Anatone delivered 2-to-1 victories, with the lone exception of one of the two incorporated Asotin precincts.
