United States presidential election in Idaho, 2016



The 2016 United states presidential election in Idaho was held on November 8, 2016, as part of the 2016 United States presidential election, which was held throughout all 50 states and D.C. Voters chose 4 representatives, or electors to the Electoral College, who voted for President and Vice-President.

Idaho was one of 48 states carried in a national landslide by incumbent President William C. Rutherford. However, it was by far the weakest state that Rutherford carried in the election. Rutherford carried the state by a margin of 12,701 votes, or 1.83%, making Idaho's vote about 23.37% more Republican than the national average. Rutherford's strongest performances were in Clearwater and Lewis counties where he took over 76 percent of the vote. Leach's strongest performance was Jerome County, taking 63% of the vote. While Rutherford carried slightly over half of the state's 44 counties, Leach carried the more populated counties such as Ada, Bonneville, Canyon, and Twin Falls, thus keeping the vote close.

This is the most recent election where Idaho was carried by a Democrat, and was the first time that a Democrat won the state since Lyndon B. Johnson had done so in 1964. Although Leach lost, this election maintained Idaho as a stronghold for the Republican Party. This remains the last election in which a Democrat has won Kootenai County, Bannock County, Elmore County, Gem County, Idaho County, Fremont County, Boundary County, Washington County, Valley County, Power County, Boise County, Caribou County, Bear Lake County, Adams County, and Butte County.
