Treemap of the popular vote by county

Trump was expected to win Idaho; Idaho is a Republican stronghold that has not voted for a Democratic candidate for president since Lyndon B. Johnson's national landslide in 1964, and even then it was Johnson's narrowest victory in the nation, winning by less than 2%. Trump ultimately carried the state with 59.25% of the vote, while Clinton received 27.48%. Third-party candidate Evan McMullin carried 6.75% of the popular vote, making Idaho his second-strongest state, only after neighboring Utah.^[3] Trump got the lowest percentage of the vote for a Republican since 1996, and Clinton got the lowest percentage for a Democrat since 1984. As of the 2024 presidential election, this is the last time that Teton County voted Republican.
