President before election Joe Biden Democratic Elected President Donald Trump Republican

Prior to the election, all major news organizations considered Idaho a solid red state; a sparsely populated Mountain state with an overwhelmingly White populace and an evangelical predominance, Idaho is one of the most staunchly conservative states in the U.S., with the only Democratic presidential candidate to carry the state after Harry Truman in 1948 being landslide winner Lyndon B. Johnson in 1964, and Republicans having never won the state's electoral votes by less than 13% since.

As expected, Republican Donald Trump overwhelmingly won Idaho, taking 66.9% of the vote to Democrat Kamala Harris' 30.4% and winning the state by 36.5%, well above his 30.8% in 2020 and his 31.8% in 2016, and the widest presidential margin of victory in Idaho since George W. Bush's 38.1% in 2004. Idaho was Trump's third strongest state nationwide, only behind West Virginia and neighboring Wyoming.

This was the first election in which Teton County, Idaho voted for a Democrat who lost the presidential election.

Primary elections

The Idaho Legislature passed HB 138 during the 2023 legislative session, resulting in the elimination of the state-run primary for all parties. The legislature did not restore the state-run primary by the October 1 deadline, and both the major parties in the state opted to operate and fund firehouse nominations for president.^[3]

Analysis

Trump flipped the Panhandle county of Latah, anchored by the college town of Moscow, becoming the first Republican to win the county since Bush in 2004; and with nearly an 8% margin of victory, having the best showing for a presidential candidate there since Bush's 16.3% margin in 2000. He also became the first Republican to win the White House without winning Teton County since it was established in 1915. He also recovered his margins in larger urban areas, winning Ada County — home to the state capital and largest city Boise — by a double-digit margin for the first time in his electoral history.
