From 1932 to 1996, Clearwater County voted for the Democratic nominee all but twice, both during nationwide Republican landslides for Richard Nixon in 1972 and Ronald Reagan in 1984. Though the county went Democrat in the subsequent three elections, Reagan's victory foreshadowed the changing political landscape of Clearwater County, as the margins for Michael Dukakis and Bill Clinton were much reduced compared to the prior decades, with Dukakis winning the county by only 6 votes in 1988 and Clinton winning by less than 7.5% in both of his successful runs for the presidency. Beginning in 2000, Clearwater County has voted Republican in each election, and the only time the margin got under 10% was in 2008. In 2016, Donald Trump became the first Republican to win over 60% of the county's vote since 1928, defeating Hillary Clinton by an astounding 43%. In 2020, Trump increased his vote share again, defeating Joe Biden in the county by 45%, and in 2024 improved yet again, defeating Kamala Harris by almost a 50% margin of victory. It was the best Republican performance in the county's history outside of its inaugural election in 1904 for Theodore Roosevelt.
