The 2024 United States presidential election in Idaho took place on Tuesday, November 5, 2024, as part of the 2024 United States presidential election in which all 50 states plus the District of Columbia participated. Idaho voters will choose electors to represent them in the Electoral College via a popular vote. The state of Idaho has 4 electoral votes in the Electoral College, following reapportionment due to the 2020 United States census in which the state neither gained nor lost a seat.[1]
As expected, Republican Donald Trump overwhelmingly won the Gem State, taking 66.9% of the vote to Democrat Kamala Harris' 30.4% and winning the state by 36.5%, well above his 30.6% in 2020 and his 31.7% in 2016, and the widest presidential margin of victory in Idaho since George W. Bush's 38.1% in 2004. 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.
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% in 2000. He also became the first presidential Republican to win Ada County — home to the state capital and largest city Boise — by a double-digit margin since Mitt Romney in 2012, and the first to ever win the White House without winning Teton County since it was established in 1915.
The Idaho Legislature passed HB 138 during the 2023 legislative session, resulting in the elimination of the state-ran primary for all parties. The legislature did not restore the state-ran primary by the October 1 deadline, and both the major parties in the state opted to operate and fund firehouse nominations for president.[2]
